To each their own but I just sold off my Surface 3 because I HATED using Windows 10 as a tablet OS and I'm usually a pretty big Microsoft fanboy. I had an iPad 4 which I traded in for a Nexus 9 which was later traded in for the Surface 3 and I miss that iPad so much. Compared to Android and Win 10 iOs is just soooooo much better as a tablet OS IMO.
With this price I don't know if I will end up going with the iPad Pro but I'm almost certainly getting another iPad within the week.
I agree I have Windows 10 on my Yoga 2 Pro laptop and it works fine. Im not "anit-Windows" by any means
Would I want to hassle with Windows on the go needing quick info? no way.
