Re:Does anyone really like all-in-one devices? (Score 1)

what about a phone, with a switch to say what mode you are in, and a touchscreen to do funcionallity, so depending on the switch, you have a different interface.

This is actually an very interesting idea. With the interface exported to a single touchscreen display, you could make the switch pretty big and easy to handle. There are still some problems though. Lots of the things that are different about the devices aren't software interfaces discrepancies - they are hardware. Camera lens, phone speaker and microphone, display, etc.

Also, touchscreen interfaces have their issues. They are more difficult to operate in direct sunlight (a big issue if you need precision interaction), they require more power to operate than just having a plastic button, and you have to actually look at the screen to press buttons - you can't just "feel" around for it. This is mostly a problem for the music player functionality.

Still, it's an interesting idea.
