I feel like I maybe shelled out a bit too much (even tho i saved £75 overall with staff discount) and dont feel its entirely worth it.
HOWEVER last night I found out a buddy of mine has a 46" sony bravia 1080p set so I went round there with the PS3 and was simply amazed (mine is currently hooked up to an old 32" sony sdtv but i've tested it before on other ppl's 1080i sets).
I dunno whether it was because of the 1080p or whether it was just cos he'd set up the tv up properly but it definitely looked a lot better on the 1080p sony than the 1080i samsung and 1080i panasonic(?) I'd tested it on.
Guess what i'm just trying to say is this, PS3 is worth it if you can access the full HD experience in 1080p.
On a more ontopic note...Here's some comparison shots of upscaled ps2 games.
