Kickstart has a point. It is quite expensive to pay 104 EUR only to try OS4. Amiga Forever is sold at 40 EUR. It could be good idea to create free downloadable version and maybe let it timeout after few hours to motivate potential customers.
Asking the wrong people, talk to Hyperion if your not happy about the price.
Maybe there should be a downloadable version, but at the moment there isn't.
Besides its not that much in the grand scheme of things.
Bet you buy lots of XBOX and PS or even steam games. So for the cost of two games, your almost there.
The thread title is "PPC Emulation in WinUAE" not "why does OS4.1 classic cost x amount".
