OK... my $.02:

The *biggest* problem I've seen with the platform has been Nokia's strategy to try to provide everything without refining first. That would be the crux of why they themselves say it's not a consumer product yet, because many things are partially-implemented and many things require community solutions to complement what Nokia provides (e.g., a camera that only works with tablet-to-tablet calls). That's very different than if Nokia didn't provide these partially-implemented features at all, BTW, because it perpetuates a feeling of brokenness and incompleteness that wouldn't be there if Nokia had focused on a few, key applications and had slowly rolled in extra functionality later. Every point of incompleteness becomes what Henry Dreyfuss would call a "point of friction" where the experience is bad -- and since people remember bad experiences more than good ones (scientifically proven!), you end up with an unsatisfying product. [In case you don't recognize the argument, this is Apple's approach -- don't implement unless it's complete -- and it's been ridiculously successful in the last decade.]

The prime example: I don't complain about it being a bad PDA because there are no PIM apps. There's a philosophy that if I want those features, I use a web service, I install 3rd party software, or I buy something else. Done. And I'm cool with that.

Every time I find something exciting with it (e.g., reading reviews from Pitchfork and then downloading tracks from eMusic directly to the device) I face extremely basic features missing (e.g., no album art, files sorted out of order, song titles jumbled) that other devices have had solved for years. It makes the tablet the most extreme love/hate relationship I've ever had with a gadget. It's the saying "jack of all trades, master of none" made corporeal.

But seeing the course this device has held since the 770 (which I've also owned; e.g., that damn RSS reader) up until this OS2008 release, I don't have the confidence that Nokia is going to be able to take this where it needs to be anymore. It's still the best for what it is right now, which sadly says more about how others are failing than how Nokia is succeeding, and what it's really doing is making me extremely hungry to jump ship the moment a proper competitor appears.

It's not unsolvable, but 2008 *is* going to be the year of the MID, and they are going to be up in their armpits with direct competitors (e.g., the mylo 2 has touch/Skype/Flash for YouTube/etc.). I would certainly like Nokia & Maemo to survive it.

P.S. I too have the SD unmount problem, and it's something that never happened in OS2007 but did appear after flashing-without-restore.
