This is really a no brainer. None of the other models have Bluetooth support, so if you want it you need to upgrade. I love the idea of using a wireless earbud, but I have not been able to try it out myself. An earbud is the only thing that is supported, however, so don't expect to be able to use Bluetooth to allow your laptop to be able to surf the net while sitting on a park bench. I was told that you can write programs to use the Bluetooth capability to communicate with other hardware, but it can't do that out of the box. |
