Well I bought myself a Nexus 7 tablet last weekend and I'm well chuffed with it!!
It's the first Android device I've owned but already own an iPad 3, iPhone 4 and 5. There's going to be a huge market for a cheaper alternative to Apple products. In a way I prefer Apple's iOS for a phone and even for a tablet, it's slicker, simplistic in a good way and tactile. But Android is flexible, widgets are a great idea and offers all the same functions.
For a main tablet round the house I'll gladly take my iPad but for a relatively cheap, equally powerful, equally capable great tablet, I'm loving the Nexus.
