USB ad-hoc networks > Ethernet lulz?
Seriously... I only have 100mbps on my ethernet... and it really only transfers at about 10mbps (partially because I only transfer between my laptop and PC, laptop being wifi) so this could be pretty sweet for transferring files between them.
I don't think it's the USB that's giving you the problem with the speed for your flash drive, Vilkku, it's probably just the flash memory itself. Older flash memory tends to be pretty sucky at copying small files - as is ethernet + wifi, actually...
Anyway. I need to get dressed.
