HP is showing off the Photosmart A640 and Photosmart Premium All-in-One, which are wireless and touchscreen printers. The printers will let you sync up with your desktop and laptop computers, as well as with mobile devices that have Bluetooth support. You can edit your pictures right on the printers' touchscreens. That sounds pretty cool as long as everything works. I haven't had much success with printers in the past.

The additions round out the line that includes the much-touted Photosmart Premium with TouchSmart Web -- for which today HP announced the opening of its "App Studio" and the HP Photosmart C4700 All-in-One Series and HP Photosmart Plus All-in-One, also previously announced.

The company WiTricity thinks that, in a few years, we won't have a need for certain types of power cables thanks to wireless power. Although not a new idea, the practice of wirelessly charging devices has just started to come about. I get tired of plugging in and unplugging my devices as they need to be charged. This technology could really come in handy.

Eric Giler, CEO of WiTricity says that power transmission over several feet is an obtainable feat. He states, "Five years from now, this will seem completely normal."
