Before I start this reply, I have to say tat it's late and I've had a few tins of beer....
I have been an Amiga user for almost two decades and overall it still remains my favourite computer to work with, but as far as I can see, the Amiga (hardware and software) is defunct technology.
We all used to say :-
My Amiga boots faster than your PC... Still true, but now with XP (my wife uses it, not me), the only time I have to reboot is with a major service pack or when I go on holiday - Not an argument anymore.
My Amiga makes better use of it's resources (memory, disk, etc.) - Resources like RAM and hard drives are so cheap now, who cares.
My Amiga multi-tasks better than windows - Still does, but there was so much hacking, kludges and non OS-friendly software, it became about as reliable as British Rail.
There are fewer security risks on the Amiga - Only because too few people use it and it isn't worth targeting.
I will still use my A1200 (I plan to teach my son basic computing / programming with it), but what made the Amiga great has either been emulated, copied or suppased by Windows and Linux. I don't think it will ever again be affordable. There's just too much catching up to do. It pains me to say it, but we all know it's true.
I write this from a Linux box (Authentication, file server, DNS server and proxy server) - There ain't no way Bill is taking over in this household.
Posting with regret. :getmad:
