Well, since you've called me out...

Why am I feeling discontented, you ask? Simple: This is the second time Nokia have ****ed the community over in terms of updates.
The first being FiF and Fremantle WRT the N8x0. It could be truthfully argued that the N8X0s aren't powerful enough (God knows I have fun playing my videos on it) but the N900? The excuse is that it doesn't have a capacitative screen. Please. I'm sure I've made better excuses to my teachers about my homework.

Helmuth has provided a list of bugs Nokia WONTFIX (not at all or in Harmattan) and Nokia have said themselves that they won't provide MeeGo officially. The resolution of this report especially makes me laugh. A bug has been found in one of Nokia's open modules, a patch has been prepared but we have the FiH ****. Now, if I'm not wrong, the FiH resolution was slapped on the report before PR 1.2 was released. This wouldn't be so bad were it not for the fact that Nokia, once again, aren't providing it for the N900.
An update to the kernel (Nokia's build, at least) was provided with PR 1.2, n'est–ce pas?

Now, you see, Nokia won't fix bugs themselves or provide an update themselves. The reluctant side of me can agree with that; Nokia don't have all the time in the world but then not releasing the code to the community - the same community you're happy to use as an excuse for your update policy ("Oh, but the community will provide a version") - just reinforces my belief. Someone compared them to cowboy builders earlier. Except you can call another builder to fix a mess caused by the previous one. It's expensive and not appealing, sure, but you have the option. Nokia's closed source stuff? Well... some alternatives to some things exist but they're not guaranteed to work as well and for the others...

I will *****slap anybody one time who mentions the community build. Why should Nokia be praised for making the community do what they should? How will it differ to Nokia's offering on the next device? What's the guarantee that a MeeGo update won't break one of many Nokia's closed source components in the future?

From what I understand, some components will be opened. I've heard libcal will be one of them. Great for hackers... if you're using an N8x0. For the N900, it means **** all but providing a slightly more future-proof MeeGo. Look up sysinfod.
For the rest, Nokia have given their permission for special images to be hosted containing those components. Woohoo! Break out the party poppers, people.

No, I'm not interested in MeeGo's code. I want to see Fremantle's stuff. Why? Put it this way: My opinion of Qt mirrors Qt programmers' opinions of GTK.

tl;dr - Nokia WONTFIX many bugs and don't provide official updates to the next version of Maemo. After all this, they won't provide much of their closed source to the community, the same community that Nokia mention will be providing an update whenever similar topics arise due to their not being arsed.
