Jordan Crook also notes how much investment both Nokia and Microsoft have in this push (but it's not the last chance saloon, as we have previously discussed here on AAWP).
That said, Nokia is putting more eggs in the Microsoft basket than any other WP7 partner, and will thus bring some of the best Windows-flavored offerings to the table. The Lumia 900 is just the beginning, so whether you consider yourself an early adopter or a late technological bloomer, it’s worth figuring out whether a reinvented Nokia and a much improved mobile Microsoft are worthy of your time and consideration.
The points on the handset, especially those on the down side, are more shots at Windows Phone (lower app count, the locked down specifications, and fixed screen size), so these arguments are well rehearsed for those following the smartphones, but it's good to see them laid out once more with a bit of balance.
