Iâ€™ve been a OneNote user for some time and namely with OneNote 2007 and itâ€™s lack of Ribbon UI.
When I originally got my old O2 XDA Orbit (HTC Artemis) it came with OneNote Mobile as part of the office applications, however I was not a user at this point in time.
As time moved on and I began to use OneNote, I had upgraded the ROM on my phone which meant I no longer had OneNote.
I was left in the same situation with my Touch HD as the Windows Mobile 6.5 ROM I am using doesnâ€™t include OneNote, however when I attached my phone via USB today so that I could flash the Radio and the ROM with fewer builds, I noticed a popup from Office 2010 which 2007 never showed.
(I have attached the phone via USB before, but itâ€™s always been with Office 2007 installed not 2010 like now)
This is similar to the way that AutoRoute used to work â€“ If it detected a suitable Windows Mobile device it would offer you the installer for PocketStreets (which was great in itâ€™s day).
Clicking the balloon opened the ActiveSync installer and started running the CAB file on the phone.
All in all it doesnâ€™t look at different on the device to the OneNote has changed from previous builds, but itâ€™s nice that the application is being offered out to people from the PC to allow you to use OneNote on the move if you canâ€™t natively on the device.
