"why Nokia threw it away and went with Windows Phone 7? Because only geeks wanted "normal unix workstation in your pocket"."
So you are comparing Windows 7 mobile with Meego ? Interesting. Even though Meego is/was geeky, it is still far far better than Windows 7 as a mobile platform. Also, regaring "unix workstation in pocket", now Nokia will soon realize that there is no pocket where there phone will fit in; sorry, but they went completely antipodal to their core strategy. There is no need why anyone would want to use Nokia on Windows 7 when there are Android and iPhone serving different user bases.
Another thing being - geeks - not the same when it comes to mobile phones, I have seen plenty of non-geeky people who wanted to change/mod their phones to help them better, look at Cyanogen Mod for instance - it is not just geeks who are using it.
