The Acer Chromebook 14 has been one of the more popular Chromebook's from Acer in recent history, and that's due to the fact that it is built so well. It has an aluminum chassis, which makes it look good, but also sturdy. It sports a 14-inch display, instead of that usual 11.6-inch display that most Chromebooks has, and has 4GB of RAM. That should be plenty of RAM for most people to get what they need to do, done. Especially since it is only running Chrome and not a full operating system. It's also worth nothing that there is 32GB of on-board storage available here, which is still plenty for most people.
Currently, the Acer Chromebook 14 does not run Android apps, but it will. Google has confirmed that it will, eventually. They have been taking their time in rolling out this feature to Chromebooks, to make sure that users are getting the best experience possible here. Battery life on this Chromebook is pretty good, we're looking at around 10-12 hours on a single charge, which is quite normal for a Chromebook these days, actually. You can pick up the Acer Chromebook 14 from eBay (seller is Best Buy actually), and it is a refurbished unit, but it does have a warranty available.
