Yes, for 11 years

I've posted my story here before.
My 36" RCA 4:3 HDTV died last year after 10 years. I replaced it with a 40" Sony. I ran the RCA at 800x600 and now run the Sony at 720P 16:9. I can go to 1080, but that's too small from 10 feet away. I will while doing photo editing up close. Sometimes I push it to 1080 while watching DVDs or HD downloads played from my computer.
Of course, My computer isn't what it was back then, either.
Other inputs are antenna and cable TV with a DVR.
