In an earlier post, I wrote about a friend having problems with his new computer. It came with Windows Vista. Long story short, he's downgrading to Windows XP in order to get all his devices and software to work.
I'm sure you know someone in the same situation. It's a great opportunity to show folks just how powerful Linux is. Check out this youtube.com video of Linux running on an older system. It's pretty amazing.
How old is the system? Well, the video author states that he purchased the system in October of 2000, and lists the following specs: PIII 800 Mhz, 128 MB RAM, GeForce 2 MX/400, and 32 MB RAM.
So, when one of your friends is having problems with their Windows Vista system, show them this video. It's inspiring. So much so, they just may dust off one of their own old computers and install Linux themselves. (It'll run better than Vista!)
