Query: Reliable and fast

The 1GB Microdrive has worked well in a Toshiba e755 Pocket PC. It mounts as a folder, just like with flash memory in Pocket PCs. It's fast, silent and reliable, although does draw more power than normal CF cards. The price is right. If you have more to spend, wait for the upcoming 4GB (later this year) and 7GB (and also a rumored 10GB version) early 2004. The new ones will be made by Hitachi.
