Problem with going with a thing like that is that I use a Wifi card, since my primary use for my Collie is SSH and VNC control of my server and desktop.
Right now, I dunno what happened, but I reformatted my CF card like mentioned in another thread (umount /dev/hda1/ and then mkfs.vfat -F 16 /dev/hda1) and when ever I put it in, the damn thing takes like 5 minutes to load up, and during that time the Zaurus is locked up. If I try take the card out during that time, it will reboot. Card works fine in my digital camera. Because of that, I am gonna wait and use another CF card (have another one coming in the mail), because I dont want to hose things up.
BTW, has anyone noticed the stock ROM for the Collie not freeing up space after you delete something? I typically have to reboot in order to free the space up, which is a bit of a pain.
