Why the Nexus One? Because I get to deal directly with Google and don't have to wait for Rogers to release software updates. Our Rogers LG Eve is still on Android OS 1.5. The Nexus One runs on Android OS 2.1.
The LG Eve running OS 1.5 can't invite multiple attendees to a meeting which is important for the on the road executive. This was addressed in Android OS 2.0 plus with 2.1 you get Turn-by-turn GPS, Google Earth, etc.
Nexus One now compatible with the AT&T 3G network and shipping to Canada
Rogers Wireless: Welcome to Canada, Google Nexus One!
I'm also keeping an eye on the Samsung Galaxy Spica for $450. If Rogers release OS 2.1 for the Spica it should be a good phone and less expensive than the Nexus One.
