I feel so old reading all this.....
I remember the first computer I ever used didn't even have a hard drive, used a 6inch floppy to boot....it was this: http://www.obsoletecomputermuseum.org/oliv_m24/
Olivette, with green monochrome screen, then windows 95 came out, got a 286 with a 20meg hard drive and 16colour monitor
Also had a Texas Instruments that you plugged into the TV and used a cassette player to load battleships, took about 5 mins to load the program.....analog baby! Oh, lets not forget the Commodore 64.
Now I'm rocking a 2 year old HP Compaq Presario with 2Ghz processor and 160gig hard drive, or something like that.....screen blacks out every now and then....but otherwise it does it's job.
