This got me off on a "surfing" tangent today and it seems that all the companies that are trying this concept are having their fair share of problems. Like Microsoft Vista

it's a good concept but doesn't seem to be ready for prime time just yet.
Since the other "grid players" charge 5X or more than MT and they seem to have similar problems in one way or another it seems inherent.
Like Dan said they probably haven't had time to way-oversell it yet (to the point of causing big failures) but the entire "Grid" concept (IMHO) is a way to use technology to handle overselling without overload (i.e. rather than juggling accounts on oversold servers just add more boxes to the "grid" and it takes care of itself)
I imagine sooner or later they will all start getting it all worked out (or one will and will dominate the others), but when one company that charges 5X more and promised virtually zero downtime had flames/excuses/problems etc. of being down for about a day restoring the entire "grid" from backups it would seem natural that MT would have some bumps in the road at $20
I'm not "flaming" MT or the others, quite the opposite. The concept is great, but there are lots of very complex "systems" (hardware/software/etc.) that all have to work together to make the "grids" work as "envisioned" and we all know how hard it can be just to keep a home PC "playing nice" sometimes so these high tech systems are bound to have their hiccups.
If they all worked as "envisioned" now everyone with "plain" servers would be jumping on one "grid" system or another and letting the "grid" keep everything running smoothly while we sat on a beach somewhere
