The only things holding me back from this were the price and the capacity. Even with 2x64 GB microSD cards (sold separately), this thing still only barely eclipses my 6-year-old iPod. When 128 GB microSD cards come out (since they don't exist), they're going to cost an arm and a leg. How is this still a problem?
Lapper128gb sd micro cards do exist, only Sansa make them ,(in Europe 120 € in the States I'm not sure, check Amazon). I have a Dx50 with the 128gb card, shure se425's and an AKG 451, The AKG's for when I'm walking around and the shure's for when I'm in bed, I'm a happy camper, the best portable sound system I've ever had,
Frankygth93Sansa? You mean Sandisk, right?

Right now going for $119, free shipping w/tax as applicable. Works just fine in pretty much anything that supports 64 GB cards, unless the programmer hardcoded things. I've yet to fill it myself, though the one in my phone...
