I need an Ergonomic keyboard for my new pbook 12". My wrists are killing me. I just switched from a pc with a microsoft natural (say what you will, they make a damn good keyboard) and I wish I could keep using that, but it is only ps/2...any recs? is there an adapter I could get for a reasonable amount (~$10) or do I need to shell out for a new kb. I would rather wait on that for a bluetooth one (one of the reasons I got this computer), but I am writing my thesis, and I need a quick fix help?
