I went from a 32" 4x3 480i TV to a 32" 16:9 1080p TV much improvement.
Then went to a 52" 16:9 1080p TV and it was much nicer with the larger size. Yes, the resolution is exactly the same on the 1080p screens, but the picture was better because the screen was bigger. It's one of the reasons I don't think that resolution is a be all end all.
And yes, if you get close enough you can count the pixels. So for anything larger I would definitely want a 4K TV.
