I just went out and picked up an Acer Chromebook 11. I had some money from my birthday and I decided to get a new Chromebook. I have an Acer C720 which I used for over a year, and bought a new one not because I needed to (the C720 is still working perfectly), but only because I had some money and had nothing else I wanted to spend it on. I think that is what's great about Chromebooks. You can go a buy one with your birthday money (hey, my family is cheap, what can I say).
Here are my first impressions. I bought the Acer Chromebook 11 (CB-11) for about $20 less than I originally paid for the C720. Unfortunately, when I went to boot the new laptop up, it would not boot and I had to return it to the store and get another one, which is working well. Moving all my old files over from the C720 to the CB-11 took just a few minutes. Making sure all the apps I use where downloaded took a few more. Making an image of the OS took about 20 minutes and that was all I needed to do to have my new Chromebook up and running with everything I had on the older one.
The build quality of the CB-11 is not a good as the C720. The CB-11 is lighter, but the C720 is sturdier. The keyboard and trackpad also feel sturdier on the C720. When it come to performance though, the CB-11 feels slightly faster. Also, the quality of the screen seems better to me. So which one is better? If you want something sturdier, try and pick up a C720 (or stick with the one you own). If you want something lighter, just a bit faster, and with a better quality screen, then pick up the Chromebook 11.
So far I am disappointed that the Chromebook 11 does not have the same build quality, but then again, it is faster, lighter, and with a better screen quality. I also paid just a few dollars less for it, so I guess I can say that I am getting what I paid for. In the end, I enjoy using Chromebooks, and I am not disappointed with the Chromebook 11 in that regard.
Just a note, I would not recommend the Acer Chromebook 11 for school use. I doubt they would survive the abuse. Now the C720 probably could and I would recommend it as a possibility.
