Another thing to remember if you're getting one of those new whiz-bang LCD slim TV's... Some of them are simply a monitor you MUST hook up a cable box to, rather than just the cable coming out of the wall..
My wife and I were shopping for a new TV this weekend and had no idea it had all gotten so complicated.
I would bit the bullet and just get the extra hookups, if the price is right.. But then again, I'm a guy, so that should speak for itself..
