Although I've skipped the N900 and I barely use my N800 anymore, finding that my Android devices are serving all my needs lately, I would think that it's an incredible shame that this is all it would take to dissuade you from writing your application on a platform you're comfortable with.

Although I agree that the comment lacked tact, looking past the disgraceful construction of the comment to the substance can be useful. If it's useful and you fix it, you might find far more positive responses in general. Just the same, I hope you have better experiences forthcoming whether or not you remain on this platform or I find you on another.

For what it's worth, I hadn't seen this app before and was pretty happy to see that someone wrote a good, useful application like this for new fathers, despite your fall-out with the comment.
