My internet at home is outmoded. You can't actually buy my current speed (20Mbit) on Virgin any more, and every so often they try to upsell me to the 30Mbit connection instead. But as I'm currently connected to work on a Citrix connection, downloading a game from Steam, just watched a couple of trailers, and Julie was catching up with Eastenders on iPlayer on her PC until a few minutes ago, without any hitches at all, I think I'll live for the moment.
I'm sure something will come along in a few months to tempt me to upgrade to the 50MB or 100MB offerings, but right now I can't think of a single good reason to.
