edit: sorry for the off-topic replies/rant. 
High resolution doesn't equal widescreen, at least not for 480p, which a lot of television sets support. My Xbox 360, for example, is set to 4:3 but is in 480p. And since the
TV even supports 480i, I'm really wondering why they don't offer a 4:3 mode at least for 480i and 480p. I'm not even sure if widescreen, 480i-only television sets exist.
I wouldn't mind if the 720i/720p/1080i settings were only widescreen, but 4:3 support for 480i and 480p needs to be added, the iPods and iPhone already have it!
As for supporting older television sets, I guess Apple could come out with
TV mini, which only has composite, S-Video and stereo outputs, with only 480i and 480p support in both 4:3 and widescreen. No hard drive, no wireless. A really basic, stripped-down unit. That's what I would've bought in the first place.
The AppleTV should not need a widescreen option. High def resolutions are widescreen by default.
