And that same Windows system can boot Winuae and run all your amiga programs.
Actually I used VT4.6 daily with multiple video and audio streams on a SCSI raid array. You can emulate say, and AGA CD32 games and play uncompressed video at the same time. BUT there is a performance hit, I have a dual 2.8 Ghtz Xeon system from HP.
The fact that you can even achieve that with all the processes windows runs is pretty impressive though.
The biggest pain in the but on the Amiga is lack of flicker free video as standard. The only game in town is the Amiga 3000 and the super denise- AGA modes used on other models.
