I bought an Acer C720 Chromebook as a whim just to see what I can do on it. I can tell you after 6 months I truly enjoy using the machine. For college you can use Google drive for all your work. I find that it does all I need and is better than using an iPad or Android tablet. The only problem you might run into is if there is a specific program you need to use for school. That will probably not work out on a Chromebook. I have also found that I can do all I need to offline, but I am always near WIFI and I have a 3G hotspot on my iPhone so I am always online. If you are looking to save a ton of money, Chromebook is the way to go.
What do you think?
