The MOTORBLUR technology is a huge selling factor for the Sholes, but unfortunately from what we've heard so far the VZW version of the Sholes won't ship with it. Maybe you can hack it so you can use the MOTORBLUR - I would - but the ability to have all your social apps as desktop widgets on the phone would save so much time for people into those things, i.e. many of the Gen-Y/Gen-Z customers that currently adore the iPhone. The iPhone sucks in this regard because it lacks multitasking, so you have to keep going to the homescreen to access your Twitter, Facebook, MySpace, etc, unless there's some AIO app that does it all for you that I don't know about. The Blackberry OS does have multitasking, but the equivalent Storm (touch screen, bigger screen for video playing, etc) doesn't compare in most areas to the iPhone or even the G1.
Android and the iPhone OS were created with touch screen, media playing, casual communications/social networking in mind, and the only thing holding Android back in the past and the present is that the Android handset is not widespread. With Sholes and CLIQ, we can expect Motorola and Google to profit considerably. But with MOTORBLUR (or some similar innate-to-Android technology that serves the same purpose), the Motorola devices would really eat the Blackberries and even the iPhone for breakfast. From there, Android just needs to be one step ahead of Apple to gain and maintain the lead.
