Here are three good (and un-solvable) reasons to never buy a Chromebook.
1. Good luck trying to connect to in-flight entertainment systems while flying. There is a lot of chatter on this subject on Reddit and other but at the end of the day watching streaming video while inflight on a Chromebook is impossible. Can't be done. If you travel a lot and were planning on watching in-flight entertainment forget it. You'll be watching downloaded netflix movies instead.
2. Bluetooth headset + video = disappointment. Bluetooth is getting better on Chromebooks (I hear) but you still can't use a BT headset to listen to audio while watching a movie. Audio services are better - but even these are a bit hit or miss.
3. If you are pursuing an online degree through WGU you will not be able to use a Chromebook to take exams. It isn't compatible with their online proctoring system. Bummer.
4. (maybe) As far as I know Skype for business is not compatible with Chromebooks.
I still love my Chromebook and use it often - however you'll need to find a workaround if any of the 4 reasons above apply to you.
