Nice review but before I comment further I have to ask, why is the lack of multi touch listed as a con? WM devices have never had it so why is it suddenly viewed as a negative if a device doesnt have it? A lot of recent reviews say the exact same thing and the only device that does have it is the iphone but you hardly see the features the iphone lacks listed as major con.
As for the rest of the review its good to see you actually used the device for an extended period and discovered some of its hidden nuances, personally I feel that the Omnia is probably one of the best WM devices you can get, despite not having a keyboard which some prefer. Strangely Samsung seems to have a different strategy with the Omnia - release the hardware and then refine the software over time. There are new "leaked" roms expected shortly that will add new widgets which will add another level of usability to the Omnia, though there will probably still be room for improvement. Here are a few vids of the expected new features:
