Well this looks like quite a change for Nokia. Very interesting to see the linux-based Maemo OS in action, which you can see in the video demonstration below.
Last 100 had this to say:

Nokia N900
Despite being pitched as the closest thing to a PC that fits in your pocket (”PC-like experience on a handset-sized device”) — a common theme in the marketing of all recently released smartphones — the N900’s UI appears to be extremely finger-friendly and optimized for its 3.5 inch 800 x 480 pixel (resistive) touch screen, where the previous and slightly larger N810 (4.1 inch) was stuck in a PC-centric UI design paradigm.
And unlike the N810 and, for some critics, the company’s recently released flagship Symbian powered smartphone, the N97 (see my review), the N900, on paper at least, has the processing power to match its UI and computing ambitions – an ARM Cortex-A8 processor running at 600MHz with OpenGL ES 2.0 graphics acceleration.
via Nokia can do UI design after all, Linux-based N900 unveiled | last100.

Gnome Do, my favoured linux alternative to Launchy, has just updated to 0.8 and the new version includes a “Dock” style theme. I’ve tried a couple of dock type apps on Windows in the past and I never really liked them. I’m more of a keyboard person if I can be when it comes to launching apps.
Still, I’ll probably check this out, seeing as it’s essentially a theme for Gnome Do, and sounds like it might be done reasonably well. I’ll report back if it looks interesting.
Docky is a frontend for GNOME Do (Do) that introduces an entirely new way to interact with Do. Docky helps Do become more directly involved with your desktop by providing a persistent mouse based Dock interface while remaining true to Do’s keyboard only interaction. Being tied directly into Do allows Docky to be adaptive and dynamic. As your usage patterns change, so too does Docky. For everything Do can do, Docky can too.

(Some might say – just get a mac, and to them I would say “shove it”)
