That computer is 13 years old. You’re like Homer Simpson and his sandwich that was killing him with food poisoning but he couldn’t give it up.
And you can get a Windows 11 computer for less than $250 from Walmart, or go even cheaper and get a Chromebook for a little more than $50 if you really want to go cheap (if you don’t need Windows 11, just want something with a compatible browser). Suggesting that you need a $1500 computer to be able to visit the SDMB is absurd.
Expecting a computer to last forever is kind of crazy. If your computer was 3 years old and you were griping about obsolescence, I’d be completely on board. But 13 years?
