So I assume that not adding North American 3G while they were at it was just a minor anagement-oversight...

This will apply mainly to their high-end $60 "DataConnect" unlimited plan (formerly "LaptopConnect") which is required for tethering. Note that tethering on lower-grade AT&T plans is a flat-out violation of their TOS. DataConnect Unlimited users would have to mainly watch out for how much video they download in a month. For example downloading a 45 minute TV show from iTunes is around 500 MB, so if you downloaded 10 shows in a month you'd hit 5 GB right there. The carriers do NOT consider these plans to be equivalent to your home Cable/DSL broadband connection.

Nope

Their booth is always the size of a small town

What I'm dying to know about:

2008 models of DVD Recorders with built-in ATSC tuners (such as the popular Panasonic DMR-EZ47VK) which output the full HD signal without first downconverting to 480 then upconverting it. LG and Sony also make such units. All current units downconvert the HD signal first, resulting in a trashed picture.

Who's this for? Owners of the earlier "HD-ready" TVs who want a combo unit which can act as both a tuner to watch live OTA HDTV, and record it (in SD) to DVD.

(groan) oh brother, things like this have been announced since at least the 1950's, always "coming real soon, not too expensive, build it from a kit". Wait a couple of years and see what happens...

I wonder if it will still be Windows-only

Comcast badly wants to be as fundamentally evil as Verizon, but their management is far too incompetent.

Martha used to regularly feature tech segments with David Pogue on her original TV program.

Does anyone know if this will be region-free, like some earlier Helios units?
