Totally agree. The performance improvement is very small for the length of time we've waited for these. I appreciate CPU supply was to blame, but still.
As usual, no sign of a spec for the SSDs they're supplying. I was horrified when I got an Xserve with an Apple SSD and it had the performance of a 2007 SSD. About 90MB/s. Pathetic by 2009 standards and simply embarrassing by 2010 standards.
