Could you point to where that model is "widely available"? It doesn't seem to be on amazon or newegg, and I'd really like to get another one (or two). It's my favorite keyboard as well.
There seem to usually be a few available at any given time on eBay or Amazon. But yes, getting harder to find unfortunately. And now I have competition...
That's why I like it so much: I've been using thinkpads for years and got used to the feel of the keyboard, and also the trackpoint, so I wanted it when I was at a desktop too. It's really nice to not have to move your hand to the mouse for small motions, although I do still use a mouse for extended things like aimless web browsing.
