I'm not a huge VOIP fan, or rather I like the idea but I wonder if it will survive interaction with the technology at the moment. Certainly for mobile. I must admit I barely use our landline and, if it wasn't free with the internet bundle, I'd probably drop it.

OTOH I've been trying to Google Desktop. I had to find an email I'd misfiled and it it managed it, pretty damn near instantly.

Quite impressive. Something actually really handy.
