Not Me! I don''t buy bleeding edge technology, but when new stuff that's significantly better has been around long enough for prices to drop, it's time to buy.
Just where would you freeze technology?
When I started studying engineering, we used slide rulers, freaking slide rulers. No thanks.
When I bought my first VCR in 1979 (mechanical tuner, not cable ready, one program start/stop) it was super in 1979. But it and three newer ones I bought over the next 25 year don't hold a candle to my old circa 2005 Series 2 Tivo (with lifetime service). No thanks to going back.
And the used computer I bought in 1980, complete with cassette deck for storing programs. Belongs in a museum. I'll stick with this old XP laptop until microsoft stops supporting XP. By then they will have most of the bugs out of Win 7.
The 1997 car I drive is far safer, more reliable, and gets twice the mileage of the first (used) car I bought in 1977. No thanks to going back to that POS either.
I watch an old tube TV that's updated with a digital converter box/analog Tivo, but when it dies of old age I won't have any problem adjusting a a new HDTV. Or maybe just buy a used tube TV for next to nothing.
