Well I've had a Panasonic 42" plasma for 3 years, and it's lovely. No DVI though, just AV, component and VGA. Showing it's age.
Wonder what the trade-in price would be.......
The number of hours I watch it, the screen life is about 12-15 years, and I'd expect to change it before then anyway. You can repair anything but the screen, but who do you know who'll fix, rather than replace, a CRT these days either?
