I've been looking at various tablets for a while now. I'm an artist and I will go to Best Buy just to draw on the tablets that they have there, so I'm pretty sure I'll enjoy drawing on a tablet of my own. Anyway, the Electrovaya Scribbler seems like a very nice slate, but the fact that the USB ports are unpowered is distressing. I've had a USB drive that wouldn't work in non-powered ports. I don't know much about PCMCIA USB cards, though. If I get one of those and put it in the PCMCIA slot of a Scribbler, will it be powered or unpowered? Or is there some other way of getting around this strange limitation of the Scribbler?
