2GB miniSD Card - 80X
outstanding
I recently bought a Motorola Q, it has some internal memory, but not nearly enough. I picked up a 2GB Mini-SD card, and BOY is it nice.  Too bad they don't have a 4GB version yet.  I encoded my 40 Year Old Virgin DVD to DiVX, with great quality, and it only took about 450 megs on the card (about 1/4th of the space) and threw on tons of mp3's, my nintendo emulator with games, and installed a bunch of smartphone apps. Still having space left. You could EASILY fill this bad boy up without trying too hard, but it gives a whole lot more space then the 50 or so megs the phone has free when you get it (motorola Q) would also be excellent in any device that takes Mini-SD cards.
