Nokia's problem is that their left hand isn't talking to their right hand.
Take all the recent announcements in regards to their new Ovi portal with a music store and the new n-gage gaming platform.
NONE of those will work with the N800.
Hell, they even dare to think they can somehow compete with iTunes with their Windows-only music store. Their own people are saying you'll need Microsoft's Internet Explorer in order to even buy anything from their online stores outside of the new phones themselves. iTunes might not be all that but one thing the iPod can do is sync with iTunes on both Windows and Mac operating systems with several open-source solutions provided for Linux users.
Thanks Nokia, but no thanks. You would have thought they would have seen the furor over the recent decision by the BBC to deploy a Windows-only iPlayer in the UK for viewers to watch BBC programming and taken a hint.
They didn't so they don't get my money for their new "services".
OS X marketshare IS increasing pretty rapidly now under Stevie J's leadership.
