!!! Anecdotal Alert !!!
A friend of mine bought a Nokia Lumia 800 as soon as they came out where he lives. He's been a devoted Nokia user for years, having bought a N73 or whatever they were flogging back then. I remember he bought a Nokia smart phone, with a slide-out keyboard, and a resistive touchscreen panel. He then tried to play Flight Control on it (this is some years back). It wouldn't go. I mean, it would load and all that, but the screen was just so horrible, it was just completey useless as a game, because in about ten seconds you would decide never to play it again because you would need 10 seconds just to guide a single plane to a landing strip.
Anyway, the Symbian software would crash several times a day (remember, anecdote. If your experience is at odds with his, well, that's another anecdote). However, despite the crap screen, he remained steadfast in his conviction that Nokia builds proper hardware. Fair enough.
So despite Apple and Samsung building some rather nice phones, he decides he's going to stand out from the crowd and get himself a Nokia Lumia. Well, I rather approve of being an induhvidual. I think your description of the Stockholm syndrome is spot-on, though maybe it's time for a the more current Espoo Syndrome, which has the advantage of confusing people (Espoo Syndrome, what's that?).
OK, WinPho 7 has a rather pleasing interface, and the screen is proper black where it needs to be black. But no multitasking, and an OS that has become extinct three months after he bought the phone, come on. Despite the fact that his phone will never run an update after the next one (and believe me, he was not pleased that I told him), and therefore the few apps that he has will be all that he has for the next two years, he remains a fan of Nokia.
