Haha,
Reason I bought N9,
Old Nokia half dead(C1-00),
Really dig phone design, since the N9 design story video, so awesome

Clock in standby screen(First world problm: hate press button to see time XD)
Swipe UI - the kind of UI+UX I've been dreaming off(sorta)
Polarized screen(I love it when I can see and read the screen under sunlight, my job sometimes outdoorsy)
Its a Nokia. Nokia = Made of Brick (my third Nokia, previous 3 are all dumbphones, but really, really tough)
The feel of the device(+ ori rubber casing and screen protector) gives me a Me Gusta feeling that iPhone fail to give.
Haptic feedback for virtual keyboard
BH I don't really mind the lack of apps, because I just wanted a modern phone that don't suck
