Are we to presume you think that using native SDKs saves your junk software from being junk? I'm not sure how else to interpret your comment in this thread.
Having software that doesn't act like native software makes it junk. I've deleted a lot of software that was created with cross-platform SDKs that just didn't behave the way every other program on my computer did. I don't have time for that. It's a lot more likely that something created with a native SDK will behave like a native app than something slapped together with the cross-platform SDK du jour.
