Those who know me know that I love mobile connectivity. I'm always on the lookout for lighter, but fast and usable, mobile devices. I've never used an Apple computer nor do I have an iPhone (my XV6800 from Verizon works quite well). I must admit though, the newest iPhone just announced sure sounds good. The fast 3G network; the built-in (and enabled!) GPS; the (theoretical at least) better integration with business applications and software (like Exchange); it sounds like this new version will be quite a nice little device.
