You'll be wanting that memory card with the 64GB Surface Pro if MS estimates prove correct. Only 23GB of usable space?! (see

I thought my 16 GB iPad was bad about usable space but it isn't THAT bad, lol. After living with it for a month I do wish I had at least 32 GB though. A few gigs of music, a few gigs of useful apps, a few gigs of games (Baldur's Gate is omghuge) and I'm out of space. No room for a movie on mine at the moment.
I also understand people who want to have a larger music collection with them at all times without dragging around a wifi NAS. I recall ending up with something more than 30 GB when I ripped 300 CD's back when. And that storage need doesn't count someone who wants a few movies with them when they travel.
