I still think I'll pick it up with my post-xmas dollars. I have a usb keyboard hooked up to my PS3 right now, because I have to type in my PSN password each time, since I have kids that I don't want wandering about the PS store. But I've had to repair that keyboard once already - did I mention I have kids?
A keypad like this, that lets me do some websurfing but that's unlikely to be damaged by the young-uns sounds pretty good. I've got a Treo with an even dinkier keyboard and I type just fine on that. I think I can manage this.
