Why Not Just One BIG monitor?

I am a total junkie when it comes to computer monitors. Seems like you can never have too much screen area. As great as the technology is, it still can and needs to go much further. The resolution is still very low. Sure, you can have a screen eight feet wide, but it's still the same res. I suppose there is a practical limit to where your eyes are not going to comfortably focus and the distance you have to move the mouse is too large. As of yet I have not seen this limit in action, however. Dual monitors are awesome, and I would be glad to go for three, maybe four. (I was thinking three across and one up in the middle) At work I have a beautiful Apple Cinema Display (the only LCD I've seen which doesn't suck) and a trusty 21" CRT. At home I have two trusty 21" CRTs. Oh sure, they aren't as sharp as the Cinema, but they're nothing to be sneezed at either. Okay, that's not entirely true, I sneeze on them quite often, but any overspray is quickly wiped up.

But I was looking at the Cinema Displays at Apple's website today and I thought, "Ya know, why in the hell bother with multiple monitors anyway? Why not just one BIG monitor? I mean, screw the bezel in the middle! Why put up with that nonsense?"

Why settle for this...

When you could have THIS!

Sure, the dual sharkie is cool, but this rig would be the fuckin' Megalodon! No stupid separate hardware, just one continuous image. While I'm fantasizing; now let's imagine that instead of 72-96ppi this thing was 300ppi! No more silly ideas of pixels anymore, cause you just can't see them without a loupe.

Perhaps there's a better aspect ratio than this, but my point is... although multiple monitors are cool and efficiency-increasing, they're essentially just a half-ass measure because they break up the image into pieces. It's like printing a poster on a letter-size printer, tiling is a pain in the ass.
