It's a pity though that it's only RS-232 and not Parallel or PCMCIA,
as the top speed of the RS-232 port is 115200 baud, which is 14.4KB/sec... 70 seconds to copy one megabyte,
and that's not considering any filesystem/translation/protocol overhead etc... worst case maybe even 2 minutes per megabyte...
So it's useful for doing things like taking backups or loading files/games onto the palmtop,
but not for interactive use, eg running games/apps straight off the USB stick...
I'd love to see someone come up with some firmware to have it support a USB mouse and translate the USB mouse proto into RS-232 Microsoft serial Mouse proto,
that would be really cool, being able to use modern USB laser mice...
