I have to disagree. Harmattan has only the N9 and N950. Out of all of the WP7 phones, the Lumia 800 is better than all of the rest of the WP7 phones, HTC Titan II probably excepted.

But each phone OS needs a model that all others aspire to be. Google got it right with their Nexus line. Those are to be the "experience" phones for that OS - so throw the most up-to-date OS, updated hardware and features, then have them trickle down to the other phone manufacturers.

WP7 finally has one with the Lumia 800 and 900. A "halo phone", or flagship - finally for WP7. Hate WP7 as much as you may want, you have to look at each and every mobile OS and you will find that each of them have had a "flagship" of sorts.

I don't see Nokia trying to be like Samsung. I see Microsoft trying to find their flagship and push it upfront like Google does with the Nexus line.

You do know that the manufacturers have to vie for the Nexus line designation?
