While Eyefinity is cool, the breaks between the screens really bother me, to be honest, they look shitty. Just come out with a higher resolution monitor so we only have to have one power plug in and no breaks between the screens. What the hell ever happened to those 43" and 47" wraparound monitors that NEC and ALIENWARE were supposedly making 2 years ago? Even if they were based off of old technology, it should be easy enough to tranpose the thought to LED monitors.
The breaks behaves much the same as frames on glasses, even with thick frames, you no longer really notice them once you're focusing on the action on the screens.
I'm going to guess that curved screens will never come to LCD monitors, simply due to the cost of manufacturing giant curved sheets of glass. OLED will probably be the next good option, but that will only happen once the prices come down low enough where people won't have to choose between buying a new BMW or a monitor for PC gaming. I'll bet that even 5 years from now we won't see triple-wide single unit PC monitors being common enough to be affordable. PC gaming isn't enough to push an expensive brand new form factor like that. (And the TV/movie/console industry will firmly hold on to the current 16:9 aspect ratio for a long time to come.) Multi-monitor with thin/no bezel will be the only way to go.
