Steve, if you are reading, just to chime in, when you theme the episodes around specific platforms, there's really little choice than to vote for the worst one out of the 5, because everyone needs the upgrade almost equally, and picking the worst one gets the most value out of the money. I think if you had 5 random PCs with various platforms, it would be a tougher choice, and more interesting to watch.
Anyway, voted for Joel, but good luck everyone.
