I recommend you to have some flexibility these days specially when uploading software to extras-devel. Once you are there it's easier to get feedback from user with devices. Now that the N900 is launched reporting bugs publicly is easier for many people.

extras-devel is now conceived in a way that you actually don't need much external feedback to be there. extras-testing is the place to get human feedback.

Also, having your software in decent condition in extras-testing or at least extras-devel will make you a better candidate to get fresh hardware sooner...
