On the first point, since Android is open source and I can't download all of that source either I see no reason why the partial codebase of iOS does not qualify.

Where can I download Moto-Blur?

the second is at least a questionable claim, given that language preferences vary so much.

That has nothing to do with it. The fact is Objective-C make code injection incredibly easy, which means it's much easier to hook into and modify specific parts of existing applications.

It's not about language preference, it's about a specific side effect of iOS software being written in Objective-C.

I'll be reading a book and then realise I've been on auto-pilot for the last 3 pages and actually have no recollection of what I just read.

How exactly do you buy things ONLINE?

Agreed - hard to believe this is from still frames.

By the by, do SI users measure their weight in newtons (the correct unit) or kg (from what I remember from when I lived in Germany, the one they actually use)?
