I have a laptop the company let me use about a decade ago, give or take a couple years. Its installed OS is Windows 95 and it has a mammoth 32 MB of RAM. (At the time, it wasn't half bad!)
Today I decided I'd try putting Linux on it. I did research to find out the most newbie-friendly Unix variants. At work I burned a Mandriva Linux CD, and at home I tried it out on the laptop. Result: failure. It won't even run from the CD, let alone allow me to install it to the laptop.
A little Web research revealed that 32 MB is not enough for many versions of Linux. I had higher hopes for it, considering that the windowing and multitasking Amiga OS ran just fine in 512K. I may try burning a "Damn Small Linux" or "Puppy Linux" CD sooner or later, but for the moment, my brief spurt of enthusiasm for Linux is waning as fast as it waxed.
