Apologies as this isn't DIRECTLY Mac related, but I will be hooking it up to my MBP, so... Our local electronics store is having a sale this weekend on a 50" Plasma HDTV. We really need a new TV, and we're thinking this would be a great buy. Initially I was stoked with the $999 asking price, but apparently it's only 720p. Is that much of a deal? Will it look stretched with my 720p content? Is it even a deal with 720p? How much would a 50" 1080p Plasma go for?
