My option isn't really in there. I've got a functioning TV and as long as it is working I won't rush off to buy a HD TV. When the old set gives up I'll probably look into buying a HD-TV. Not that I'm that that impressed with the high definition I usually have snot and yoghurt smeared all over the TV set anyhow.
So I'll vote, I'll buy one when the old set brakes down, but only because it seems to be the new standard.
If the word got out that 3-D TV was on the brim of being introduced I'd much rather wait for one of those.
