as far as hardware vendors go, I think meego could be attractive to all the same ones that android is attractive to now, motorola, samsung, LG, HTC

they will take meego core and slap on some chrome, decals, and a few value addedd integrated apps and call it meegoblur or meegosense ui, etc. I think these vendors will also appreciate a little more the ease of adaptation to hardware vs android. I think winmo probably has the easiest hardware adaptation.

as for the carrier situation in the US, what a horrible situation. CDMA probably will not die for at least 2 more years as everyone transitions to LTE hopefully, so I don't think Nokia is going to go after the locked in Sprint/Verizon market and they are #1 and #3or4 in US subscribers. perhaps some of the other manufacturers might do cdma hardware though so as long as meego spreads wide and Nokia sticks to its unlocked guns, I will be happy.

Where intel fits in this, i don't know. Either tablets or other direct powered devices(car nav entertainment, TV) or they have a great mobile chip in the works. IMO intel would be wise to get a serious chip out there with all the requisite mobile feature set. I have got to believe they are working on it. If they can make a winner, they will blow ARM out of the way with their scale.

worldwide if you combine the scale of intel+nokia+(some other large device manufacturer like samsung or LG)

I think the future for meego is good. they are taking the track of android which is blowing by iOS as we speak, only more open and more adaptable.
