"If you must focus on Symbian, at least include more article on how Symbian devices interface with Linux computers and Linux-based accessory devices."
I actually did this a short while ago, in a feature on the Nokia N800 internet tablet which uses the Linux OS but can access the internet through any bluetooth phone (including Symbian ones):

There's a Nokia-created open source UI for Linux called Maemo which sits on top of Linux in their N800 and 770 internet tablets, and they also have demos of Maemo running on desktop PCs. You can find out more here:
http://maemo.org/
They've also embraced open source to some extent on Symbian, Nokia's new S60 web browser is an open source one for example.
I actually think Maemo is a better UI than S60, although Maemo would need severe tweaking for it to work well on a physically small screen with no touch sensitivity.
As I said in the news post above, the problem with Linux is that the phone platforms are so splintered. Symbian has the advantage of being unified to just two platforms (S60 and UIQ) whereas Linux doesn't yet have a single clear flavour or flavours that developers can rally round.
What would be interesting is if Nokia put S60 on top of Linux, but that's a huge can of worms as far as the Symbian world is concerned.
From a competition point of view, Symbian is perhaps healthier than Windows Mobile because Windows is entirely controlled by Microsoft, whereas Symbian's ownership is split between many rival phone makers. Nokia is the largest Symbian shareholder, but they only hold a minority of the shares so they need the support of their rivals in taking big decisions. Nokia tried to buy a controlling stake a couple of years ago when Psion sold their shares, but the other owners successfully blocked it.
