[1.5, or later] Cell Phones/PDA's

So what if you had something like a cell phone or PDA that you could use? Some useful functions could be to locate your home or other computers using GPS or rednet (not sure how the "side" thing would work though…), or you could make a function that the turtle gets your coordinates via GPS, and navigate to you? I think it would be neat and add so much more possibilities to the game, because you don't have to put down a computer and do your code/program/etc. each time because you could keep programs without putting down computers to destroy them and lose programs (unless, of course, you have a disk drive…). You could also have some way of having an SD card in the phone that you could put in a computer disk drive. What do you think?

You can label a computer (label set <name>) and it will have a unique ID and won't lose programs on destruction.

I still like the idea of an item that you could equip/use to access the interface rather than having to place/break it every time you wanted to do something.
