Can I get a HUH?!?!?

HELLLLLLLOOOOOOOOOO! I would appreciate a heads up from now on as it pertains to any changes in television, electronics, computers and cell phones. I recently "upgraded" to a wonderful 47" HD/LCD/120hz Vizio Television. YUP! I am a sucker. That being said, the t.v. is AWESOME and would be completely acceptable for the rest of my t.v. watching life, however I turn around two days after purchasing said t.v. and it's already out of date. WHAT????????????????????? Are you freaking kidding me???? I just spent a hard earned paycheck on what I thought would be the best, top of the line t.v.'s and it's already past tense. CRAP! Don't get me started on Cell Phones, those rat %^^$&^$&!!!! are worse thieves than the government and that's saying something. I want a guarantee that the product I buy will not be outdated or obsolete the moment I plug it in, and for that matter I want a product that was actually conceived and made in the U.S.A Thank you and Good Day!
