Check the
archives for apps an such. Play MP3, go create stuff with lunapaint, use EUAE for your Amiga apps. AROS is still a Work In Progress (WIP). If your expecting a shiny OS with all the bells and whistles, your going to be disappointed for a bit longer as alot of items are in developement. It's saving grace, it's not costing you a penny for the past, current, and future developement plus AROS is open source. How much more do you expect?
