Just to point out that this is T-Mobile USA specific. In Europe, T-Mobile are already running 3G networks, and in many countries are now offering HSDPA data. (In the UK the T-Mobile Vario II now offers HSDPA access - and they have a few decent flat-rate tarrifs)

The UK Slingbox has already started shipping - and was on sale in PC World in the UK this weekend (although it isn't due to launch until the 31st May apparently)

I bought mine in Central London - and it does indeed have an integrated Freeview DVB-T as well as analogue PAL OTA tuner, alongside S-video/Composite AV inputs. It doesn't have SCART sockets on it (too big I guess), so doesn't have RGB input, but it does come with a SCART pass-through adaptor that allows you to tee-off a composite feed from a SCART daisy chain.

I'm happily slinging from Freeview and a Sky+ satellite PVR, to both a PDA and a Laptop.

Great product - very well designed and easy to use.
