Thanks for all the information. I'm going to keep my eyes peeled on Mac Mini's and go from there. I figure I can buy one, try out the OS and if I decide I don't like it can sell the Mini and get back what I paid. Nothing to lose really. Can you drag screens like in the Amiga?
Turns out the oficial Mac keyboards are only £29. I was shocked, I expected them to be a lot more.
The was one web site which I found, and then lost, which provided a lot of info on the games and had a picture of superfron playing on UAE, but can't for the life of me find it. I was wanting to show it to a friend who's Ex Amiga and now using MACs. Does it ring any bells with anyone?
