You need to be mindful of not reading things out of context. You appear to be making a generalisation based around what you are using the machine for today. In the days of the A4000, A1200, A600 and CD32 the A600 was the worst. The one I had was not even capable of supporting a hard drive. Yet my A1200 was accelerator friendly out of the box and ran rings round the A600. The A600 was really never one thing or another. It was not really suited as a games machine and was just not able to be expanded with ease. It really was a bit of a toy generally and used by those that didn't really treat their computing seriously. And if you were giving advice in the day there is no way you would suggest to anyone that wanted a machine that would last to consider anything other than a 1200 or 4000 which were the current best machines for the period. The A600 was pretty much dead in the water the day they released the A1200.
And for the comments from another about the 2000... different era.
When I bought my 1200 the shop was split into two halves. On the left was Amiga and on the right was PC. When greeted at the door the shop attendant would always point me to the more fun and entertaining Amiga section. There was only A1200s and A4000s on show. If you wanted an A600 you would have to go to Dixons or Jessops where they sold them with their cameras and video players. My sister had an A600 just to play Pictionary. The A600 just was not treated seriously, sorry.
As for today, well that is a different story. A great tool and fun to dabble with. Just get one that supports hard drives. No amount of creative mount lists ever got my first 600 to work with a hard drive. So I bought another that did. I must have a dozen 600s. Don't use them. The 4000s and 1200s still rule here.
