Does that make the next version; the "Lime Pie" Android 5.0 ?!?!?

Btw, a friend wants to get a (non-iPad) tablet.
Its going to be used around the house, a present for his mum. 7inches is out of the question.

What are the best (Wifi) ones out there?
I'm thinking between the lines of the Transformer, Note 8/10, Nexus 10. Xperia tablet is nice, but doesn't seem to have any stand out features.
Any thoughts?
