I have the same sentiment and when more apps run in the cloud, and all one needs is a fast web browser, that will make it more of a possibility to do coding, digital media editing, etc. from anywhere with available peripherals.

The entire home wall video monitor in the beginning of the movie Total Recall (first version) would be great to have everywhere. Just as you change music you could make your environment look like anything and this same technology would let you grab a little near by space to use as a screen. Too expensive now but in ten years, perhaps.
