The Boy Genius, that lucky dog, has gotten his hands on a BlackBerry 8300. He says:

It’s a little thinner, and smaller than the BlackBerry 8800. I guess you could call it a cross between the Pearl and the 8800 series.

BG didn’t get too deep into the BlackBerry 8300 features, however, he did note that the unit that he had did not have Wi-Fi, but, did have OS improvements such as spell check, full screen video mode, and the ability to create folders on the home screen to which you could ad any application.

BG has more than a handful of BlackBerry 8300 pictures posted over on the Boy Genius Report.
