Off topic, but there's the SAM Flex units if you want to buy a PowerPC Amiga. The CPU is a PowerPC 440, which is a bit dire spec-wise compared to the G4, for example, but the architecture is impressively solid (I used one at a Commodore festival in Las Vegas and AmigaOS 4 -- now that it has a useful selection of web browsers between Timberwolf [Firefox 3.5] and Origyn Web Browser [WebKit] -- is really quite practical as a day-to-day OS now).
