(The development options are fairly confusing though. For C/C++ development, the only Symbian dev avenue worth considering nowadays is "Nokia Qt SDK", which is surprisingly nice. Java seems to be essentially deprecated, but higher-level options like Python and JavaScript through Web Runtime are available.)
Google should support this guy: http://groups.google.com/group/android-ndk/browse_thread/thr... and be more open with development options in general. Official support for Mono or Qt would attract a lot of interest.
I agree that Qt is "surprisingly nice". Personally, I enjoy the iPhone UIKit framework, but the Qt SDK is almost as good (and in some areas better). I don't have much experience with the WRT, but in the N8 the demos I have seen are quite impressive performance-wise.
[disclaimer: I work for Nokia, take all I say (on this matter) with a grain of salt.]
Edit: Minor spelling.
Humans are fallible, and so you'll get false positives (and negatives) for what, in retrospect, seem like very bad reasons. However, the one thing you won't get are superstimuli—apps that the approval "algorithm" loves but people hate—because there are people inside the algorithm.
Even so, I can't even sell on Android market because I don't live in one of the approved countries.
Even before appstores, the most popular way to get software for a PDA/Smarthphone was with dedicated store sites, with the important difference that they bled you dry for cash.
