I have another idea, I think I'll add it as another solution too..

What if a value added application/service (for ex. Sports Tracker or Ovi Navigation) is offered freely with the optional condition of installing a "system monitor service" which will submit crash logs on user selected schedule/behavior?

This is similar to Digsby's and/or Google's very accepted* approach (grant it freely, mine back the value slowly) but should be done in Nokia's harmless way other than already offered compromising privacy.

*: considering that we are talking about the possible mainstream customers which we are targeting at the moment in this sandbox idea.

I added Solution #7 based on the idea above

I was looking at the various suggestions etc, and bringing my teddy bear head to the table, I'm not sure about the exact differences.

Perhaps if I explain where I'm at, you can tell me what to vote for!

Once I get my precious n900, I will, after a few days playing, be up for app testing. I will be happy to report problems with the following provisos:

1) I can only test anything once the troubleshooting page is clear enough for me to be absolutely sure I can restore after problems

2) The easier and more streamlined the reporting process, the better. A single 'report this?' button (much as windoze does it) is easiest for me. If I can set preferences to always do it, even better.

3) BUT (see above) I am on a limited data plan. If I can set it so that any problems are auto-reported as soon as I connect to my 'home venue' wifi, that would be perfect.

4) No, I don't need fancy incentives: being part of the community and having something I can do (given that i can't code to save my life!) is incentive enough.

What should I vote for?

I don't need too, but some people will surely need fancy incentives for motivation (that could mean more affirmative user experience for some, people like being awarded for their "hard work" ) and attraction (IMO most mainstream users won't know that they could contribute unless they're obviously offered. Remember the power of marketing )

If existing solutions satify you, you can vote each independently.
But if you're not satistifed, you can create new solution(s) based on your conditions and wait for feedback as I do atm
