I'm still wondering when Apple will get around to buying Wacom. They bought FingerWorks to get the best multi-touch technology, but I don't think that multitouch will be quite enough to accommodate the full range of capabilities we geeks want from our tablets. The combination of pen input and multitouch offered by Wacom's Bamboo and apparently Axiotron's upcoming Modbook Pro is, however, enough for general purpose computing. (Command lines and programming are still hard with pen input because nobody has made a pen input system that is optimized for all the strange punctuation.)
