2. "Nice, more people will go away from Apple store"
3. "Developpers go where user go (and pay)" (ie iOS)
4. me: "user go Android".
5. you: "How is this at all relevant? do both"
Well, sure you can do both, but I was replying to the "user go Apple" claim above, so it is relevant, or?
There is a reality mismatch with Apple: they do nice tools, but the fact we hear about them a lot and almost all movies, screenshot, etc. seem to show only Apple products, do not mean that most users actually use Apple systems or products (except if "most users" means "most startup entrepreneurs and wealthy folks in SV")
The reality is, to be clear, that all but a tiny not representative fraction of laptops and desktops are running a version of Windows, and almost all but a small fraction of smartphones run a variant of Android.
I avoid Windows and I am not particularly found of Android, but I think not going Android is suicidal for devs, except if they do special elite or niche apps. I did not invent this myself, Fred Wilson said the same many time.
