I'd get a loan and buy a $3600 hitachi 42" plasma tv.
Oh wait, I already got one, but I paid cash for it. Hitachi 42PD78900TA. It's a euro/Australian model, 1024x1024 resolution. Looks really nice. Probably a total waste of money, but I figure since I resisted buying a 32" tube 5 years ago when I could first really afford one, I "deserve it" now.
