Actually multiple monitors has worked since the MacSE. Radius made a video card 
for the MacSE to drive a 20" b+w monitor around 1986 and you could use both 
screens just fine. It was very useful.

Looking in my bedroom alone I see several macs with multiple monitors:

G4 with a cheap OEM HerculesII GF2MX and retail 8MB ATI RagePro VR

6100/AV using built-in video and the AV card, which is a PDS video card

PB520 with a B+W LCD and a built-in video port (non-mirroring)

Pismo, similar to above

Mac IIfx with two nubus cards

I've also owned/used a 7600 and a Q950 both with multiple monitors. The 7600 
used three, 15, 20, and 19" B+W portrait. In fact I don't think I ever used a 
setup where the monitors were the same resolution, size, or aperture ratio.

In fact given my first mac was that souped-up MacSE, the only mac I've ever 
owned which did not use multiple monitors was a PB145! It's one of those 
technologies which quickly paid for itself in gained productivity (unlike 
virtual screens which have the opposite effect).
