Guy does know what's talking about but there are some limitations to his tests - which to be fair he's pretty open about in the post.
The biggest challenge is optimising for SPDY is different to optimising for HTTP and so many of the test sites may have behaviours that aren't optimal for SPDY.
In addition to Google, Facebook and Twitter are/have deploying SPDY so I think we can be sure it has benefits.
