The office just replaced my aging cell phone and pager combination with a BlackBerry 8830 World Edition. It's much restricted by our IT department (and rightly so), but apart from the useful alert filtering, it's obviously inferior to the iPhone. The keyboard is a bit easier to use, although typing non-alpha keys with one hand is impossible. The web browser is grounded firmly in the last century, and the map feature is useless unless you already know where you are, where you're going, and how to get there. Plus, the warm, friendly screen-based buttons become a lot less friendly when you realize there's no touch screen. Stupid trackball thingy. Unfortunately, our firm doesn't support the latest BlackBerry models.
