How good is your computer?

I'm working on something that's almost 10 years old. When I go to certain webpages, the computer hums loudly, because it can't handle the javascript. I can't play games, and I think the thing is finally starting to crap out. Everytime I start it up, I pray that it works. I do a rain dance just to make it turn on, because sometimes, it really doesn't want to.

I haven't even been able to use Unity to try to develop any games lately, because my computer wont run that program anymore. Also, I can't watch some videos on here, because the video gets fucked. I think I might need a new computer soon... I hope old Betsy can last me a few more months.

What do you browse the net with? Desktop or mobile? How good is your device, and what else does it do for you?
