Touch computing....

We've been seeing all kinds of touch screen computing devices for years - some better than others. In the last several months PC manufacturers are putting out more and more experimental looking devices and a lot more investment is apparently now going into this stuff. I'm now genuinely becoming convinced by the real world applications for some of these UIs so long as the cost and implementation are reasonable.... Microsoft have been working on an OS for the last few years and the wraps were taken off this week. Take a look at this link.. I'm impressed and could see some trendy restaurants experimenting with their "surface computing" soon. It'll be great to see how this technology continues to develop in the coming years. It just needs a "killer app" or system that makes the advantages really stand out. On mobile devices I think it'll be the iPhone interface from Apple...... but how long before the mouse has a genuine rival on full size machines?
