I haven't cackled with laughter at anything this techie for quite a while. It's a graph, showing assorted sales forecasts for Intel's Itanium 64-bit processor over the years, showing just how ludicrous some of those forecasts turned out to be.

It's also part of the main Wikipedia entry on Itanium, and I'd like to thank Guy Kewney of Newswireless.net for drawing it to my attention.
