And yet if you keep having the next best thing, you'll have everything (except a surplus of cash).
Gotta pick your battles and decide when you feel the time is right. I haven't yet felt the time has been right for myself and my eight-year-old plasma to part ways yet. For me, it's like if they stopped making manual transmission automobiles: sure, the new cars may be better in every way, except if they ain't stick, they ain't ****. I'd rather ride out my last manual as long as I possibly can, for the added benefit/enjoyment I get out of it and knowing I won't be able to again with any new models (that would be a sad day if this really happened).
I'm waiting for non-plasma/non-projector technology to get motion right for movies, for one. That, or I'm waiting till I have a place where I can dedicate a room to a home theater and get a projector. Also waiting to see on what Samsung does with their emissive quantum dot technology. Also also waiting to see if I can cash in on the stock market sooner rather than later.
