the last thing anyone needs is a bunch of whiz-bang devices that can only talk to each other. like i'm going to replace my blackberry, pda, cell, etc., with these motorola units. my kingdom for an open-standards way for my palm to talk to my phone, my blackberry to my palm, my PC to my digital camera, etc. the technologies -- wifi, bluetooth, IR, whatever -- are there. cooperation is the killer app. ;)
