Bluetooth, you saw me stand-alone
Matt likes Bluetooth a lot: "Hey everyone! I've got the internet in my pants!"
I've used Bluetooth to get online (Mobile + PDA) and while, like Matt, I've enjoyed the connectivity freedom, the first time I used it Bluetooth crashed both my Nokia and my PDA. The PDA crash resulted in complete data loss.
Since my PDA has since crashed in that way without outside help I tend to blame it on the Dell Axim 3i (you get what you pay for, darlings), but it's still put the fear of Bluetooth in me.
Trying to sync my mobile with my PC is also a daunting task, it can take a while before the Bluetooth connection sticks.
Always nice to read succes stories, though.
