I recently discovered and interesting blog for ubiquitous computing. I am very interested in being connected all the time. However I have serious demands for my computing equipment and I am often caught in the power vs power paradox. To get heavy duty computing you have to sacirfice power/battery life. This guy has been trying to deal with this and we have much of the same equipment.
