Right, but I read his message as saying that about desktops. Since he 
said he has only used 64-bit on servers since 2006.

I also read his message as saying speed differences were not 
sufficiently different to outweigh the baggage of 32-bit.

I don't believe he's really addressing high-end hardware in his 
comments (given whom asked), where I suspect "32-bit" isn't even in 
the lexicon these days.
