The better line would be "I was OS2005 before Maemo took over". The point is that Maemo hasn't developed along a straight line with a clear vision of its purpose and future. There was a break, and from my POV there's two Maemos.

Maemo initially used to sell the idea of a secondary device that does things you wouldn't do on your phone or laptop because of its form factor.
It used to hold a promise of 1:1 desktop like experience, including the complexity and precision required for it, but also resulting in all its endless possibilities.

These were the things that made Maemo and the Internet Tablets cool then. (And that made me buy them.) Maemo sure was cool right from the start.

Then there was the 180° turnaround in 2008 that finally resulted in Maemo 5 and the N900. Primary device with the form factor of a phone, restricted phone experience rather than full desktop experience.
This is cool, too, in some way, but it's no longer what Maemo and the Tablets used to be. It's a whole different game now, recycling the leftovers from the internet tablets.
