No, I don't upgrade my RAM since I don't do many activities on my computer which require a lot of RAM, so I'm fine with the amount of RAM I have on my PC.
I only see myself upgrading my RAM if it breaks, and needs to be replace.
It's pretty easy to do, you just need a band to get rid of static electricity before you start touching PC parts. I upgraded my old PC but I don't need to with my new one since it has 8 GB of ram.
Nah. I've been lucky with my RAM (Except for back when I had 512 MB's of DDR ram up until two years ago... And even then it was just one gig slapped on.), so I've never had to upgrade my RAM. It's normally a CPU or a Video Card upgrade I need.
I used to upgrade my PC parts more often in the early 2000s, but there are not many programs like web browsers, Word, and windows movie maker, I use which need faster parts to run. I'm also using Ubuntu Linux More which runs faster on most older PCs compared to Windows
