Re: No SD slot?
Far more useful on the ol' Transformer TF201 (which also is currently using most of its inbuilt 32 gig and nearly all of a 16GB full size SD and 16GB micro SD). The USB slot on the keyboard dock is great for shoving a thumbstick in for file transfers (or a joystick or pad for games, or even a mouse for some Real WorkTM).
On a phone however, that means big dongles sticking out the end, and some kind of adapter to go from micro-USB to full size. I may not be Apple-obsessive over neatness, but that's an ugly and potentially unstable solution when a micro SD will do.
Besides, most of the internal space is actually taken up with apps. Yes really. You know how many gigs of space putting just a few Gameloft or Rockstar titles on the device will take up? Stick a few albums and some DVD rips on there and you're full, and wondering what to delete to make room. That extra 16 or 32GB makes a massive difference when you only have 16 or 32GB to start with.
