For ordinary surfing, not a lot of difference, but for me it's one of those things like a microwave that once you have it, it really makes a difference. For the internal phone line runs, test and see if you are getting the speed you pay for. If not, a reel of cable costs ten bucks and wiring the jack takes ten minutes.

Second the Bittorrent stuff. I use it to timeshift shows I *really* don't want to miss, but it was a use that never would have occured to me.
