Do you guys just dump and upgrade?
We've just looked at some TV's today the first as a group of us but our CRT is still going strong 13 years now. I've also had my PC for 4.5yrs and that is going strong too, it only lags for photography but every day stuff it is perfectly fine. A person said we could trade in maybe even for $50 if that's possible but that's a waste and b/c we subscribe to World TV (via Sky TV) their stuff isn't HD anyway.
Been burnt 13yrs ago when we got a $900 DVD Player, haven't used it much less than 50 playbacks probably, so haven't even replaced it nor gotten Blue Ray.
I was also just a moment ago trying out a spare computer we had, the CRT monitor expired some months ago so it is not being used now. Hooked up to the LCD and it worked flawlessly. Dual Core 3.0Ghz. XP of course. Maybe we have reached a plateeu for every day stuff, I know an IT friend and he's still using a Samsaung SII. And likewise I still have a used bought laptop (1.8Ghz Dual Core), in a way I cannot get a tablet b/c it's there but I would only do that should others need it, quite ok with just my PC for photography and my cell.
We might even get another 4yrs out of the CRT TV who knows ....
