On what merit will they be trying to convice the users ?
I can imagine that for anyone using their phone to call, message, email and the occasional web visit it may well work;
On the flipside, I can't see anyone using their phone to do this and only this giving 2c either way. They will keep using what they are using because it works. If it hadn't they would've stepped of the bus a long time ago.
The compelling reason for people using a powerful smartphone is a multitude of apps and games specifically designed for droid and IOS. This is, I think, what sells them and drives people to upgrade them to more powerful hardware and better displays. We already know that a take-up of a new system relies heavily on what I would describe as non-basic use. Windows is allegedly hampered by the absence of a multitude of fart-emulators, aviary agression simulators and such. For people to accept and embrace a new means of going about their daily communication needs, you would either have to come up with a revolutionary (and possibly magical) way for them to send a mail or make a call OR offer them a 'killer application' that is not available from the competition (possibly a solution to a problem they didn't know they had before the solution presented itself). AND there would have to be a substantial immediate (and to a lesser extent future) gain to convince them to put in the effort.. If the only thing you can offer is less of the same, you are doomed.
And all I see here is less of the same. Being able to plug my phone into my monitor does not sound very compelling to me.
