Phone Arena were lucky enough to get some quality time with a prototype Omnia Pro and have written up their thoughts. There’s no information on browsing speed (one of my main questions,) the battery life or the quality of the keyboard but they do talk at length (and extremely positively) about the user interface. They also note that there’s a CPU speed setting. They call it ‘overclocking’ but as they didn’t test it, there’s no confirmation that it is. I suspect its more for underclocking in order to save battery life and keep the device cool!
There’s a video, a few pages of text and a video over here at Phone Arena.

Is still have a stack of questions
- Outside use with the OLED screen (often a problem with OLED)
- Battery life
- Audio quality
- Browsing speed with Opera Mobile 9.5 and 9.7
- Keyboard use
- Wi-Fi and HSPA quality
- Video playback rates for DivX, MPEG4, H.264
- Flash support in browser (not expected. Maybe in Win 6.5?)
And of course, I’ve got a lot to learn about the application ecosystem for WM. I’ll be looking for apps that can help with microblogging, video posting to YouTube, image posting to Flickr, posting content to my blogs, GPS, tracking and mapping and much more!

GSM Arena’s preview is up now, too. http://www.gsmarena.com/samsung_b7610_omniapro-review-378.php
It’s hardly the most thorough review, almost completely devoid of mention of it’s web browsing capabilities, and from the phsyical look of the handset it appears to be quite an early prototype. Still, it does cover some ground that Phone Arena did not.
