Nexus 7: should I go for 16 or 32 GB?

Hey guys,

I'd like to explore the Anroid ecosystem (as a current iPhone/iPad owner) and the consensus seems to be that I can't do better than a new Nexus 7.

Which size should I go for though? I'd like to keep the price as low as possible, and I've only ever owned 16GB Apple devices for the same reason. I get by with a little judicious shuffling, it seems, even on my cellphone, where I take all my pictures.

With this in mind, what does anyone think to 16 vs. 32 GB? I don't intend to put any music or take any photos on it, and I'm happy shuffling video on and off for trips. Are there any other factors to consider? Anyone who is ecosystem-agnostic know how app install sizes compare between iOS and Android?

Thanks a lot!

Mark
