I just picked up a "Flashtrax" by SmartDisk.
It's a 30GB hard drive for uploading my microdrives, this is not your
typical up-loader drive. It also happens to play mp3 files (I've already
got about 40 full music CDs copied to it for easy connection to my car
stereo), and has a 3.5 inch flip-up color screen (you can upload file and
play music without opening the screen, BTW).
It is well-built and much more physically substantial than other gadgets of
this type I've seen/handled), has a high quality Toshiba hard-drive,
upgradable firmware (already did this), replaceable/swapable battery, and
