Doesn't that speak to his point? Either smaller memory and more nodes, or more memory and less nodes. Why not do apples to apples? (This feels like the benchmarketing going on in browsers, which, at this point, is largely meaningless.)

Edit: on the other hand, this is an endorsement of the current wave of "per node performance stinks, let's avoid rewriting software for an extra year or two by throwing SSDs at it." Great for hardware vendors!
