I don't take any offense at all. I have a large collection of amigas and videos, but I would still disagree.
1) it is actually more like 10 seconds, but hey, that is a great amount of time - given nothing else is loaded. My A3000 used to take 20 seconds with everything loaded. My current mac takes about 30 seconds.
2) cool for sure, but unix and linux have the same functionality
3) smooth yes, but unstable due to memory management. I still think mac gets the nod here.
4) Unix and linux based variants have this: including mac.
5) not too familiar with these other than I just use them from time to time.
6) never got into this, so once again I am ignorant on this one
7) Shell, again, linux, unix, mac -- can run with gui

Ok, I wish this was possible with other oses -- still very cool for the amiga - but spaces and screens for unix and linux and mac is a nice tradoff-- amiga still way cooler.
9) efficient ram, but then again, it has many issues with memory protection.
10) all modern system have a multitude of co-processors where the cpu is not dependant.
11) unix and linux do well here
12) mac has it through image files.
By the way, I would never compare Windows to Amiga. Windows still has a lot to steal from the Amiga!
