To some degree, this seems like an unfair complaint. Like expressing displeasure with a VCR's longevity shortly after the introduction of DVD. If you buy any descent-quality TV today there's no reason to think it won't last you many years. My Philips LCD panel is four or five years old (I bought it with one of the Bush tax rebates, whenever that was) and it's more-or-less indistinguishable in terms of quality and features from anything you can buy in the store today. I mean, it doesn't have 3D, or 120hz refresh, so I'm not saying that technology isn't constantly improving as it always will. But it's got a perfectly nice 1080p picture and lots of inputs including like 4 perfectly good HDMI ports. There's no reason to think this TV won't do everything I want it to do for the next 5 years. Content's not going to shift to 4k any time soon.
Part of my point is, I doubt an Olevia rear projection television made at the same time as your Sony would be any better. Don't get me wrong. I've definitely been happier with no-name or smaller-name devices plenty of times in my life. But the reality is that the Wega TV was purchased at an unusually transformative time in the TV industry (shift to flat panels, shift to HDTV, HDMI vs. DVI). That time is over and has been for some time. The TV market is not fraught with unknowns right now. Any HD LCD or Plasma from Vizio, Sony, Panasonic, Samsung, Sharp, LG, or pretty much any other manufacturer is going to serve you fine for many years going forward. And prices are pretty fantastic right now. Maybe I'm wrong, but I sort of suspect that we don't spend more on a TV today any more than we spend more on a candy bar or a soda today or a house than we did 20 years ago. We also get paid more.
Don't get me wrong . . . some panels have far better pictures than others, with better color saturation, contrast, black levels, refresh-rate, bonus features like Netflix streaming, etc. Some are better values than others. You should do your homework and get the best bang for your buck. But this is no different than it's ever been.
