I am going through this at the moment. First impression is that is pretty much what I am, as a end user, looking for. Congratulation !

Slide 5 : Is there really no other way to make a donation than with site like PayPal. Perhaps it should be integrated with your ovi account ? I just see this coming : "I wanted to make a donation but I was brought to PayPal. Is this a scam ? PayPal is not mainstream. If an end user got a Nokia phone and s/he is brought to Ovi.com for donation or better yet if it is integrated in the OS and told that, say, 2$ will be deduced from his/her Ovi account then I am sure donations would increase.

Slide 16 : Just a small comment. I would trigger the survey after the application has been launch for the fifth time. When I close an application it is often because I have something else do to and don't want to go through a survey at that time.

This whole process must be quick. An example :

Hi you are launching this application for the fifth time would you to give a feedback ?

YES --- NO --- Take survey later

If user says YES then :

Rate this application : 1 - 2 - 3 - 4 - 5
Donate to developer(s) : 1$ - 2$ - 5$
Go to application web page (where you can ask for enhancement for example).

As I am not always online I would like to be able to complete the survey offline. I guess it is possible to store the survey localy and then when the phone is connected it can be sent.

Slide 21 : Is it possible to have something a la Windows which automaticaly send a report ? If it takes more than 1-2 minutes you are at risk the end user will get tired and close the bug reporting application.

To make it simple : Speed and ease of use are key elements for bug reporting, donation and rating.
