if you go with a G3 you can get a Pegasos 2 for 299

Peg2 is a much better deal...it dosent have the buggy articia chipset...and its much cheaper while still bieng better performer (it should be anyway) with DDR/Gigabit ethernet/etc... AmigaOne dosent have OS4 yet anyway... its essentially a Linux machine... bieng sold as a 'someday amigaos4' machine...
