Big issues with these.
As a grass roots IT support guy I have issues with such bottom of the barrel computing.
1. They are not really powerful enough to run Windows 8/8.1. I've had in £250 laptops with AMD E1 CPUs in them and they are terrible. Truly embarrassing performance and I'm a big AMD fan.
2. They are so cheap and 8.1 is such a hassle to re-install at times it makes it not really worth it financially to re-install and fix them back up if they fail. A lot of the so called user friendly restore options don't really work if the machine gets too screwed up and they do for some reason.
From my point of view the ultra cheap Windows with Bing machines don't make much sense. Get a Chromebook instead because at least it shouldn't crash.
