WP7 better customer satisfaction than Android, not quite iOS yet.

Yeah, I'd agree about the Arrive being "underwhelming" in the hardware department, because I want the big screen and front-facing camera, and as Eric said, I believe both are promised for fall release... hopefully Sprint will pick them up this year.

Dual-core would be nice, because I think it would entice developer support for better apps and games, but only if there's an appropriate compensation in RAM too.

4G coverage is still pathetically weak on the carrier side. I was in Pittsburgh last night with my boss, and his EVO wasn't performing any better on 4G than my Arrive on 3G, and we both use Wi-Fi most of the time anyway.
