This is not to excuse Nokia in any way, but in the past few years the cell phone slash mobile computer business has changed rapidly, to put it mildly. Some companies were in a great position (lacking legacy) to capitalize on some of those changes (Apple, Google). Nokia was hampered by, ironically, its past successes.

With benefit of hindsight it's easy to look back in time (as I often do) and say "Crap, Nokia should have done this or that", particularly with Maemo. They didn't. So they have made some hasty and even counterproductive moves especially in the last two years, to try to correct mistakes.

The vision was right. The execution was off. So, the guy ultimately responsible was fired and his replacement is already showing some good decisions (hardware and software platform consolidation, partnerships, staffing, etc).

Knowing these things, everyone who isn't simply a rank troll should be mature enough to move forward, with or without Nokia.
