All right, have to chime in. I have been a Maemo user since the first release of the 770. Used to be on the boards here years ago, alot, but lost my username and password during a transition period. I had a G1, and a Mytouch as well, both Android devices. Now, I have played with my buddy's Nexus 1 with Tmo 3g, and it is pretty nice. I actively went back to Maemo 5/N900 after Android. I found more freedom with the N900, the linux box is so robust, and the ability to surf the web like I am on a laptop is second to none on any mobile OS.

I used so many apps on android. They were great, but they distracted the crap out of me. Stocks were available on N900, but did I really need that wootoff app and ebay app? No. And in my profession, you should never be distracted. Yes, Android's google maps are more robust than Maemo's ovi, but there are pros and cons to both devices. The N900 is a man's phone. When I pull this sucker out, I still marvel that I have a linux pc with a phone stack, and I can terminal whatever I want. I rooted and terminaled both my Android phones, but Java was so limiting.

Get Android if you want all the apps in the world, and you have more free time to play with them. They are nice toys. And very convenient in some ways, and distractingly inconvenient in others.

Get the N900 if you want the internet tablet/linux pc that gets you through the day, lets you get on that airline site and make an emergency change (which I did the other day, and could never do on flash-lite webkit browsers.) The N900 has just begun to show its full potential.
