I had the Note for a week.

Pros:
really big screen, beautiful colors, capazitive screen, screen sensibility
fast dualcore, ability to overclock to 1600MHz or more, lower voltage
many apps, google maps, adaffix
fast GPS fix
many custimozed ROM's and kernels available
2500 mAh battery
recoring videos @ 1080p

Cons:
no hardware keyboard
WLAN and 3G signal is really bad
no hardware key to switch between tasks
too many apps/services running in the background with to many permissions
I need more steps to call a random person than on N900
you need to create a google and samsung account to use many things

The Note fits in my pants pocket but when you sit or drive it's really uncomfortable.
The Cons (mainly the hardware keyboard) are the reasons I went back to my N900
