Yeah - I'm betting this is going to just work...as seemlessly and smoothly as the WP7 does most tasks... That's why I don't mind a *reasonable* time for MS to get everything right.
By reasonable - I mean early to mid FEB works for me. Pushing March - now that's too late. MS have a whole different set of expectations here with WP7 vs. say the ZuneHD free apps and firmware update release schedules.
Improvements, fixes and evolution in general is going to be demanded from WP7 customer's. The bar will keep getting higher, and we all hope MS will keep delivering. Base product is great - but we want MS to delight us... I think they will.
