I would buy another, because
i really like the bridge system. Gives me option of browsing without a separate data plan, as in iPad etc.
Native email would be nice, but the bridge solves the problem for me. If RIM would arrange for Google to add a Google Map app, the PB would have most of the things I need. I really like the screen, the ability to hook into my TV with a HDMI, the tabs feature of the browser and now that I've got used to the 'swipe' functions, I would miss that.
So I would buy another.
