N9 because its from Nokia and MeeGo which is step from Maemo and everyone know how great Maemo is

Samsung because we know Nokia is not going to support it, Maemo 5 is an example but Android us typically created for a typical hardware or vice versa but the point is you will potentially have to throw yout galaxy away once a newer version of Android is released.... I may be wrong but the experience so far suggests so...

comming bank to Nokia N9, it has some cool features such as swipe and multitasking that is truely multitasking.

Android has heaps of applications but it seems that N9 will have enough as well because Nokia is running a couple of competitions to get the apps developed and spending millions on it.

Good luck!
