I can understand not having your favorite program on your favorite operating system. It sucks. Especially when you know that 90% of the internal workings are identical on each platform.

However, speaking as someone who has done programming, it is not a simple case of just work a little harder. Usually all time units are used up. There is no more time to allocate.

It is also not an issue of just get someone to port it. Even in Qt, there are lots of little things to do to get an app to look and act correct on each OS. It still takes a hella lot of time.

So, the end result does not include the option of getting a little done on each platform. It usually only includes get it done on one platform (we hope).
