Just to drop in on this thread, I received a 750v this morning. For someone switching from extremely active use on a BlackBerry 8700g and BlackBerry Pearl/8100 and never having any experience with a Treo or non-BlackBerry smartphone in the past, I must say that I'm not impressed whatsoever. From the connect-on-demand nature of data connectivity (absolutely horrid, mind you) to the extreme conflicts between standard Desktop Manager and Desktop for WM to the lack of compatibility with Outlook 2007 (or maybe those errors were simply because of the BDM conflicts... hmm). I've just now gotten BlackBerry Connect to work (I think - let me go test it right quick) - this is roughly 12 hours after I removed the device from the shipping packaging.
Anyhow, my first venture away from Waterloo's finest has not been all that promising. More to come later, maybe.
