Leaving iOS

Looking to change things up a bit. Im on a old Iphone 4 right now looking to buy in on the android side of life.

The question i have is this:

What will give me the bes value?

Buying an LG Nexus 4 16GB and a Asus Nexus 32GB or

buying a Asus padfone 2 64GB + tabletdock

The thing is im not very happy about the size of the Nexus 4, im constantly deleting things from my 16gb Iphone to get new stuff and im not happy about it.

Listening to the Vergecast and the Mobile vegrecast i havent heard alot about the Asus padfone 2. Im i the only one looking forward to a review of it?

Thanks alot for reading !!
