That's quite the email, lots of passion. IMHO, its way too personal. This is a business / marketing decision and needs to be treated as such. Large corporations like Nokia don't respond to ultimatums. Regardless of what they do someone will be unhappy. I think what is ultimately more useful is articulating how a change to their current course could be to their benefit.

Personally I'd probably still buy a Meego-based product (in 2011 / 2012) even if the N900 didn't get it. I'm American but the iPhone and Android services are way too US-centric. I do a lot of work overseas.

For Nokia there are tons of advantages to not supporting an OS with no future, also, they would benefit from having the maemo 5 community automagically transition to Harmattan (easier said than done), which would give that community a boost and would benefit future products because of the strength of the community. A win-win in my opinion. The problem is its a lot of work, its short term pain for long term gain. That's my story and I'm sticking to it! ;-)
