Would you care to elaborate on why?

I had to work on one and didn't really see what the fuss was about. Performance still sucked compared to a Cray2. I mean it was supposed to be a Supercomputer...

I/O was painfully slow so unless you were not planning on looking at your results or your results were a few numbers it may have been ok. We were doing 2d and 3d simulations and periodically outputting large amounts of data to make movies from the simulations. It would run for a few minutes and then stop for several times that to get the data out.
