I initially got the 8800 and was pleased with it. Then picked up the 8300 as well a few days ago. Performance wise, I'm happy with both, but the screen is a lot better on the 8800. Seems like some bugs need to be ironed out with the 8300 but that just takes time. And I prefer the GPS over the camera - anyone with any discerning eye on photography wouldn't be using a phone's camera anyway.

Purely from an aesthetic point of view (being a design professional)l, I'd have to say the 8800 wins. The 8300 and its "liquid silver" casing is actually just gray plastic. I don't know where they came up with the marketing gimmick of "liquid sliver," but it's like saying my thinkpad is an "infinite depth monolithic black," when it's just black. I'm sorry to say the 8300 looks and feels a little like a toy. It's probably more similar to the look of the older blackberries but that also means it's a little dull. The 8800 looks like a glossy integrated unit and has a nicer weight to it. And again, the screen doesn't look washed out.
