A beta running on a PowerBook doesn't mean it's usable at the moment. On most PowerBook revisions there's no touchpad and keyboard support, on rev-d and rev-e only keyboard works, and that only after some usb hacking. No WiFi, no battery state control, no power management, no backlight control, etc make it unusable for a consumer IMO. PBook and iBook surely won't make it into 2.5. eMac might be a different matter though, but you'll see for yourself when it's released :)

About the price,
@Zylesea: it's funny how you bring up Polish salaries. Actually, most people unhappy about the price come from countries with much higher salaries than Poland (Germany, France, USA). Why is 150 eur too much for people that had no problem paying some 600 eur for a Pegasos 2 system is something I can't understand. I remember paying a similar amount (150 eur) for ImageFX in the past for example. I remember paying some 1500 eur for my PowerUP Amiga... A MorphOS + Mac Mini is just CHEAP compared to that.
