LOL...my first Mac was a 512k back in '85. With my experience with this, and my TRS-80, when I bought my next Mac (a Classic II), I knew I wanted the most RAM possible (4MB), but when I saw the choices of a 40MB or 80MB drive, I was there like, "Geez, I'll never fill up a 40MB hard drive."
Well...I started having all the problems pee-air described above...and then when I bought my Performa 6116, with a 700 MB drive...well, let's just say that one copy of Marathon and one copy of Dark Forces, and CodeWarrior, and...I was screwed...
Ahh, the good old days!
