I've had an A500 as my primary computer from 1989 to 1993. Among the expansions I bought were a harddisk and, more important, a KCS Power PC Board. I noticed that in the period 1992-1993, most of the time, I was running MS-DOS (4dos is great!) and decided to buy a 486DX2/66 in 1993 for a hideous amount of money. I've always liked DOS and Windows, and I have used 3.1, 95, 98, NT and 2000 (never saw use for XP) up until now.
I now own quite a bunch of computers, ranging from a C64 to Amigas and pretty up-to-date Windows/Linuxmachines, and have expanded most machines as far as my bankaccount would allow, and I might eventually completely switch to Linux, but I will not 'return' to my A1200 or my A3000 as a primary computer. I like using my Amigas, but I find both Windows (2000) and Linux (Ubuntu) to be more stable and more comfortable for my everyday needs.
