See, NOW it makes sense...

Might I add a quote from Aaron Seigos recent blog post about the N900:

"I've seen this played out many times while I've knocked around the
industry. To maintain a closed ecosystem in the face of an open one, you
have to be insanely better (mostly at lock in techniques) or have a
monopoly position. Open ecosystems far too easily generate a network effect
that can quickly trump funding, partnership politics and even quality.

There is no successful, closed ecosystem monopoly in the devices world yet.
There is Apple (who is growing, almost entirely due to there being a vacuum
to fill), there is Android (which isn't open enough to avoid the pitfalls
and pratfalls of competing against truly open ecosystems), there is Windows
Mobile (but that's all a lark these days) .. but nobody has claimed title
of Insurmountable King of the Hill (IKotH). Any of these players can tumble
down, and likely will if they stick to their closed ways. This isn't to say
they can't carve out a respectable and even sustainable niche, they just
won't define the market long term unless the open up."
