said by DarkSithPro:Android has finally become a really good OS with Jelly Bean. I do not like these manufactures installing their custom touchwiz style interfaces within the OS. It just completely ruins the Android experience for me IMO. This is why I would never get a Nook, or a Kindle Fire. Once they start hacking up the OS it becomes absolute shit and not worth it...
Well that is pretty much limited to those 2 being heavily company oriented/limited.
Most of the others are much the same one to another, but for preinstalled stuff, but OS pretty much just Android. OS wise very little difference between the two in question.
