My first OS was on a old mac... ummm I forget which because the PC was so old and it was so many years ago but it was hardly a OS. There was basicly nothing on the PC but dust and a command language similar to DOS. There was no mouse either.... just a keyboard sticking out of this small yellow looking box and it couldn't hold alot of data unless you use a floppy that was larger than the size of CD when I say large I mean very big in size not memory heheheh. Then years later I got my first PC and I was so happy I named it Windy it was a windows 95 lol I still have windy, and a few years after that my parents bought about 3 of XPs.

Im currently siting on my bed with a toshiba satellight running a XP OS with a P4 1.5GHz, 256 RAM, DVD/CD-RW combo drive, 14.1 diagonal TFT active matrix display, and a 20GB HD. My toshiba beats the crap out of my old MAC and windy95 days.
