As I said, it's not about lag, high resource consumption and all those rubbish "excuses". If that is a concern, then just make the default option as TURN OFF. When user want, they need to TURN ON with an message letting them know if they turn on this Flash, they might experience some performance issue.
It's the same as JavaScript, Java or whatsoever plugins. Does our PC browser remove them? No. You can have options to turn it off.
Removing something completely without giving option, then saying due to XX reasons are all "excuses". They are treating ALL users as dummy, and preventing people complains about performance issue in case some user face problem without understanding why.

Again back to basics: OPTIONS, not "excuses".
It's not right to say nowadays it HTML5, so no need for Flash, or Flash is super high resource consumption and all those. Don't want to provide, just say don't want to provide, be honest and frank... but then, they can't, it's a business.
It's also same like AUTO-FOCUS VS EDOF feature on camera. Saying EDOF is fast without providing Auto-Focus is "excuses"; You can switch to Sports mode which doesn't require focus or provide option to turn off auto-focus to get EDOF. But if you have EDOF only, you have no options.

For those that don't want Flash, of course, they might not understand. But because of this, people doesn't care or push, manufacturer just drop it and say, "got people say no need mah!"
If there is a CHOICE,
N9 - Without Flash support
N9i - everything same but with Flash Support
I wonder which will people choose?
Got is better than No.
