I'm reading "The Hard(ware) Choice" and it is interesting how the different schools/districts chose much different options.
ReplyDeleteI linked out ( http://www.google.com/intl/en/chrome/education/devices/ ) to read more about the Chromebook which seems to have some benefits as far as start up times and management....there is still a lot more to find out, though!
....The Chromebook also has an 8+ battery life.
ReplyDeleteAnother interesting note from the article: one school didn't anticipate the increase in enrollment (due to the implementation of the 1 to 1 program???) and suggested ordering 15% more devices than a school expects to need.
I could name a few problems that i can see with these. The main thing is that it is all stored on google docs and nothing is stored on the computer itself. Chad and I have talked about buying one of these and testing it out and seeing the performance and how they run.
ReplyDelete-- I also do not know why my name is Mr.Rodenbaugh :)
After reading more, I realize that Chromebook is quite a bit different than a standard laptop. Here is a review I found that was pretty informative...
ReplyDeleteThe software
For those unclear, Chrome OS (which the Chromebook runs) is fundamentally different to a Windows, Mac or Linux-based laptop, desktop or netbook. This is because it runs the web. No native applications exist specifically for this machine. There are apps (sometimes referred to as Chrome apps) but they also work in the Chrome browser.
Because this computer runs what many call 'just a browser' it has several advantages, as well as disadvantages when compared to a Windows machine. I've chosen Windows for most comparisons here as more people typically use Windows than a Mac or Linux machine.
Security
You cannot install Windows applications (or other native software) on Chrome OS. This means that the computer can operate more securely than a Windows machine simply because the computer knows what should be installed. If something is there that shouldn't be there, the computer will erase all local data and install a version of the software that's stored in a secure area. Once you're connected to the internet, you'll be updated to the most recent version of the operating system. As your settings, bookmarks and Chrome applications are stored by Google, they are also restored after the machine is reset and you log in. Typically the operating system is updated every 6 weeks, meaning bugs get fixed pretty quickly (important bug fixes will arrive more quickly) and new features are released quickly, too.
and the review continues...
ReplyDeleteGetting things done
This is where the big problem is for some people; you can't install Microsoft Office, Adobe's Photoshop or other software packages. You're limited to software that's delivered through a website. Most people are perfectly comfortable with using things like Facebook, Twitter and email this way. The web offers some pretty powerful tools, though. For instance, pretty sophisticated image editing software exists on-line, as do audio and video editing tools. Using the massive resources of the internet (typically referred to as 'the cloud') means that video editing and other resource-intensive tasks can be made dramatically quicker than doing it locally. Make no mistake though, if you do need something like Photoshop it's just not possible, unless you use software specifically designed to deliver 'normal' software through the web. Companies like Citrix offer products that can do that, but given the additional cost, it's usually only big businesses that use them.
If you don't need extremely-specialised software though, there's a lot available. Google, Zoho and Microsoft all offer tools that will let you create, open and export documents in popular formats, such as Microsoft Office. There are advantages to this approach, too. Google Docs (as an example) allows individuals to use their on-line document, spreadsheet and presentation software free of charge and, even better, you can collaborate with up to 50 people on the same document, practically in real-time. This sort of thing just isn't typically possible with traditional software. Where it is, it's likely to be clunkier than a web-based tool as a website just lets you login and work.
Calendars, Angry Birds, finance tools (Sage and QuickBooks are available through the browser) are all also available in this way. It's worth checking out if the things you'll want to do are available in this way before ordering a Chromebook.
There are also many off-line capable applications. That is, things that will work without an internet connection. These include Google Documents (editing and viewing) Google Docs spreadsheets (viewing) and things like Google Calendar. Keep in mind though that this is primarily a device for accessing the internet. Without a connection, this device is extremely-limited. Applications delivered through a browser will get more and more capable over time, though.
Other drawbacks
As I've said, not everything is available through a browser. Critical things that people take for granted either aren't available or are very different on a Chromebook.
It's not possible to watch AVI or MKV video files (at the time this was written) for example, without converting them. That's a big pain for some. Printing is different too, as you can't just plugin a printer on Chrome OS and have it work. For those that are curious, Google has a service called Cloud Print, which involves hooking up your printer to the internet. This approach does have an advantage in that you're able to print to your printer from anywhere with an internet connection, either from a mobile device or any installation of Chrome. For those without a printer that can connect to the internet independently of a regular computer, you can enable a normal printer by installing Chrome on a Windows machine and running it that way.
Storage
ReplyDeleteA key thing about Chromebooks is that they come with a 16GB hard drive. This is considered very low by modern standards as a typical Windows machine will come with a minimum of 500GB and often far more.
Google Drive is Google's solution for this. Essentially, Google Drive is on-line storage. It stores files from Google Docs and will store pretty much any type of file, too. A key thing is that it integrates with the file system, meaning you can save files directly to your account (Drive can be used on Windows and other computers, as well as Android and iOS devices) and access them from whichever device you're using.
By default, Drive comes with 5GB of storage. This isn't a huge amount, but for free on-line storage it's pretty typical. Many other services actually offer much less. However, if you buy a Chromebook you get 100GB free for two years, which is very useful given that it can be used across many devices. If after two years you're using more than whatever the normal free allowance is at that point (things do change) and you've not qualified for some other promotion, you'll no longer be able to add new files. Your existing data will be accessible, meaning files will not be deleted.
Another great thing about Drive is that files can be shared with others. Google Docs files are not counted towards your storage.
Again, it's worth noting that other great on-line storage solutions exist, such as Dropbox and Box. The difference of course is that they're not tightly-integrated with the Chromebook.
Hardware (general)
This new Chromebook is running on an ARM chip, the type of processor you'd typically find in a mobile phone or tablet. That may sound slow given the demands of a typical Windows machine, but it's very quick. It boots in around 7 seconds (it feels more like 5 as the logo is on the screen almost as soon as you open the lid) and you can be on-line with your normal tabs open in under 30 seconds with ease. The keyboard is extremely responsive and many professional reviewers have remarked that it's the best that's ever been on a Chromebook, which includes the much more expensive Samsung Series 5 550 machine. The trackpad, too, is very good indeed.
The machine is extremely responsive due to it needing very few resources to operate. If you attempt to run 20+ tabs, yes, it will slow down a whole lot. But if, like most typical users, you use this for email, Facebook and the like, you should have no performance issues. Depending on your usage, the stated 6.5 hours of battery life are very close. In fact I'd suggest that you'd get more, depending on screen brightness etc.
Other hardware
On this particular unit you'll find one USB 2.0 port, one USB 3.0 port, HDMI out (for putting what's on your screen on a bigger screen, like a computer monitor or TV) and an SD card reader. External USB hard drives work fine in my experience and many phones are treated properly as mass storage too. However certain devices such as external optical (CD/DVD) drives will not work at all. As a commenter noted, I originally forgot to point out that this machine has no moving parts because of the type of hard drive used. This means the machine is extremely quiet and doesn't get hot.
ReplyDeleteMiscellaneous
It should be noted that since Chromebooks are essentially stateless (that is, they have little personal data stored on them) they can be wiped at any time without a problem and you can start over. This also means that they can easily be shared and Chrome devices (a desktop version, called a Chromebox also exists) have something called Guest Mode, which allows a friend to browse the web without accessing your settings or bookmarks and when they're done, their browsing history is automatically deleted. For those with whom you share your Chrome device regularly, you can add them to the list of permanent users.
Summary
Essentially, if you use the web most of the time (this is what most computer users do) or want a second machine that can be used without any technical knowledge for that purpose by others in your household, this is an ideal device. If, however, you like to play a lot of 'real' video games or access specialised software, chances are that this device isn't for you. That said, this device is cheap enough that you can buy one for the couch or to use while you watch television. Due to the price of this machine, it's most likely to be compared to a low-end Windows machine (which are typically very slow) or a tablet, such as a Nexus 7.
If you want easy web access and don't care at all about typing, I'd suggest a tablet. A good quality tablet can (at the time of this review) be had for $199, including a high definition screen. But if typing and web access matters to you, I'd seriously consider this device.
Hi all:
ReplyDeleteCouple things....
Did you see you can split your keyboard into two halves....it makes typing much easier if your good at texting. Just take two fingers on the keyboard and spread them apart....then reverse to bring the keyboard back together.
Some must have apps: "Educreations" Virtual white board that will also record your voice...could have a lot of potential uses
Powerschool app....if you want to use this one you need to change some information to log onto our school....see me if you need help
Have a good time with your new tool!!!
