Meego is actually a merge of two former operating systems - Maemo (developed by Nokia) and Moblin (developed by Intel). I tested Maemo on a N900 and was not impressed.
The UI's look nice, but I question whether they will get significant developer support.
Nokia's userbase doesn't mean anything because it's mostly from featurephones and not smartphones. Also, their share is dropping. In India, for example, Nokia's market share dropped 20% in the last year or so. The same is happening in the UK.
Well, Samsung already overran Nokia in featurephones sales but Nokia is still a leader in smartphone sales in Europe.
Nokia 5800 and 5530 are the most popular smarthones in Europe but believe me when I say that I have no idea why.
I agree that Nokia's popularity falls with each year. Personally I never understood why their phones are that popular in the first place.
comScore breaks down smartphone OS stats in Europe | dotMobi.
Its MobiLens survey for July 2010 shows that 51.2% of smartphone-owning respondents in the UK, France, Germany, Spain and Italy have Nokias. However, comScore warns that Nokia's EU5 smartphone market share has fallen 14.4% since July 2009 - during which time, smartphone adoption in these countries has grown by 41% to 60.8 million people.
Symbian is still the most popular smartphone OS in the EU5 by usage, with 54.4% of respondents using Symbian phones. However, that share has fallen 14.4% since July 2009 too, with both iOS and Android growing their shares in that period by 5.3% and 5.6% respectively.
So still for every Android user there are almost 10 Symbian users.
I can also see a very strange trend amongst people I know - some would only replace their Nokia phones with new Nokia phones, no other company. Very strange but pretty common in Europe from what I see.
And Nokia phones really have very strange tech specs. To name a few they still tend to prefer resistive screens, slow processors and that damned Symbian in their new phones which is probably the worst mobile OS.
It would be a very good move for Google and Nokia if they started working together on Android. I mean, if Nokia relesed a few Android smartphones it would boost their sales and introduce Android to Europe on a larger scale. But Nokia had made a lot of very strange business moves lately which resulted in their sales drop. And they still do.
