- Yes, the 486-33Mhz blows the 68EC020-15Mhz, but the 68040-25Mhz blows
- the 486-33Mhz or even the 486-50Mhz :-(

- There is some things VGA cards lack : sprites, multiple screens (copper),
- blitter and then SPEED ! Having to blit with the internal cpu (a 486,
- though) takes some precious time that could be used to do some kind of
- calculations...

- You're totally wrong, here. There are many expansions announced for
- the 1200 : 68040, DSP, SCSI-II and BridgeBoard.

- There is a ?PROPER? way to multitask on PC : OS/2 + 16 Megs of RAM + 30
- Megs of VM. Of course, it doesn't compare well with the Exec/Intuition/Dos
- kernal of the Amiga.
