the question in the title is something I've been wondering about a lot. I haven't worked with WP7 and do not plan on doing so, but out of curiosity this question is in my mind.
Are there technical reasons?
Would it be possible to see a community-port on windows phone 7? (like the android-lighthouse project)
Wouldn't Microsoft profit from a bigger developer community as well?
Please lets try not to use this thread to discuss our opinions about the Nokia-Microsoft-Deal, but let's stay on topic.
I'm eager to read your answers!
