Just looking for some help in making a decision.

I have moved from Apple to Android and always use Google Chrome anyway. I only really use it for Email and browsing the Internet. Occasionally Google Docs, in fact Google for everything.I need to replace my MBA and cannot make up my mind as to what to replace it with.

I would like your opinions please on the following :

I have a Sony Xperia Z1. Should I keep this and buy a Chromebook or should I sell the phone and buy the new Asus Padfone Infinity Phone & Tablet ? I know there is a difference in cost but this isn't really important as I have the MBA money ready to spend. I really like the idea of the Padfone as it keeps things to a minimum.

Many thanks.
