Can't wait for the 256 GB at $899!
Seriously though, I think this is an odd moment to introduce this. Yes, it should have been introduced already, way earlier. But today it almost feels too late with iCloud, Netflix, Spotify, Dropbox, all that. I don't exactly have a growing library of mp3 files these days. Sure, it's nice if you have a conservative data plan, but I can't say I'm without WiFi for weeks at a time too often.
i've read a lot of corporations testing ipads for business use asked for this. especially those where people need to carry around large autodesk and similar files
