1) Maemo has a real desktop browser, not a mobile browser (Android has a finger-fancied-up-but-still-mobile browser)

2) You don't need to break anything in order to "root" Maemo. It's not 100% straight forward, but it's pretty straight forward. And you don't break anything when you do it.

3) That should make it easy to do wifi tethering (hopefully), which is not easy on Android (without rooting it).

4) Maemo gives you command line access to the Linux environment. Android does not (without rooting it).

5) Maemo is compatible with many (but not all) general Linux apps. Android is not.

6) Maemo: Actual OpenSSH and VNC viewer. Android: good imitations, but still imitations.

7) last I checked, Maemo had better IM clients than Android.

8) Maemo, hopefully, still has a Rhapsody client. Android's is still on the way.
