Bought my SN last Saturday and love it!
I'm not missing my HD7... ;)
Dolphin browser from Android market is a great internet browser, and it's free.
S-Memo is a very nice note app, S-Pen works very nice with the app.
With Sygic and the 5.3" screen, point-to-point in 3D works as well or even better than a dedicated GPS.
Exchange server sync even has Out-of-Office built-in. Look at my signature on two helpful tips on firmware update using Kies and how to read Outlook Task using S-Planner. There seems to be a bug in the Inbox, showing "IRM not supported" and can't sync after one day. Sent folder, calendar, contacts and task syncs find.
The screen lag I had noticed from demo sets seems not present in my Note. Great!
With my HD7, with Tune-in playing in the background, and with voice commands from navigation app, the voice commands and Tune-in sounds are broken. With the Note, Tune-in and Sygic, I don't have problem with sound.
I like the phone dialer better than the HD7 dialer.
Battery Life is better than my HD7, but that may be due to the higher Ampere battery in the Note.
So my conclusion is, the Note is a good buy. I'm glad that the HTC Titan has not arrive here, thus giving me the opportunity to get the Note.
