Another seemingly useless product. This caught my eye because it's the first Bluetooth product I've actally seen on the shelves.
One part plugs into your notebook. The other into your cellphone allowing you to use the cellphone's modem without needed to connect a cable. Is that really so useful? First of all that plug is not small so you'd problably never leave it connected meaning when you want to use it you'd have to get it out and plug it in. Why not just plug in the regular cellphone to modem cable? On top of which it's got to use more power than a regular cable since it's got to broadcast.
I guess it might be useful in that you could leave the phone in your briefcase. They need to just integrate a wireless modem into the notebook.
