Sometimes there is a technology paradigm that just gets me excited about the possibilities. One of those technologies is multi-touch. Microsoft just announced that this technology will be coming to windows 7 and they demo-ed the technology today. Previously this technology was only going to be available (in the windows world) in Surface. The fact that this technology is going to be a part of 7 means general availability without the high up front costs of a surface only solution.
Ah .. the possibilities ..
