Shipping today, the device gets an 8.0 overall, "Excellent" rating from Bonnie.
She even posts a video review. I've posted a freeze frame from that review.
Here's her summary take:
The good: The RIM BlackBerry 8820 is the first BlackBerry to offer integrated Wi-Fi. The smart phone continues to offer Bluetooth, GPS, and push e-mail capabilities as well as push-to-talk and multimedia functions. We were also impressed by the long talk-time battery life.
The bad: There's no 3G support and no option for a camera version. The QWERTY keyboard can be slippery, and the device uses a proprietary instant messaging client.
The bottom line: The addition of Wi-Fi makes the RIM BlackBerry 8820 an even more powerful communication device for business users, taking it beyond just e-mail and phone calls.
