Nokia are going with Meego for their high-end phones- Symbian will only be used for lower end phones. The Nokia N8 will be the last N series Symbian phone.

Naturally the day after I buy the N900 (which I love so far) the Motorola Droid/Milestone is named 'Gadget of the year' by Time and a release date is given for the Sony Xperia X10 (18th January 2010). Also the first email I received on the N900 was from expansys with an offer for the Droid.
Gotta love the timing of things sometimes...
