Without taking a position on either side, I would say that maemo was probably the best positioned OS for an expanding definition of mobile computing. The much maligned Eldar Murtizan had an article where he spoke of their vertical strategy of having an OS going throughout the product line.

Nokia has the capability in 2011 of having a diverse product portfolio consisting of low priced but very capable smartphones with Symbian for developing markets and ex-feature phone users. You can see this in their announcement of sub $200 qwerty devices.
Next you have Meego powering their high end smartphones/tablets/netbooks and whatever else. Nokia has the entire OVI ecosystem (music, files, email, maps, PIM) to deploy across a system of phones and netbooks. Nokia seems to not want to play the one device game so integrating the crossplatform development using Qt was cooked up as their answer to fragmented development.

Basically Nokia is losing the 2010 battle and others have caught up so far, but they have a much better chance at success later in the year (Q4) going into 2011, whether they succeed or not remains to be seen. The lucky thing for them is that as they well know the mobile world moves in 12-18 month cycles and things can go really well for them very quickly even though their last few quarters have been disappointing.
