Should MS do this promotion?

It is generally thought that MS is making OK margins on the surface but have put them at the price they are to not muscle out the OEMs.

But what if MS ran a promotion where it gave away an entry level WP8 phone with each Surface or maybe make it a token price of like an extra $50 to have the phone included. I was thinking something like the Nokia 620 which MS could get at a good price.

This would allow them to really demonstrate the integration in the adverts.

Not only would this shift more Surfaces it would also provide a good way to increase the WP8 market share.

What do you guys think?
