well, I am C# developer of 5 years, and I had some big plans to make some n900 apps, but I really couldn't find 1 straight article that would go from start to finish on how to instal the virtual machine, to how to compile my first app, to how to run it on the emulator. After a couple days I just gave up.

I might pick it up again in a few months.

so my guess could be lack of such straightforward development support?it's a trade off, but here's how it works for apple:
you pay a fee
you get a membership and access to stuff
there is a tutorials section with sample apps and how to get started

here's how the maemo sdk stuff went
I scoured the forums

found a wiki with instructions that weren't detailed enough on how to install a virtual machine

I have no clue how to compile my first app, but it all seems to be in command line?

I gave up

maybe this stuff is only for linux gurus
