Scripts at the browser can actually speed up the display of a website, even on my 486DX2-100. Yes, I still have one that I use for testing. It depends on what the script does, and how well it is written.And you look at that as a good thing? Websites doing their best to force people's browsers to run scripts locally is half the reason things run so sluggishly (and CPUs heat up) on low-performance computers, and why using an old one can be a nightmare.
You want to buy us all decent hardware, lol?
