I am slamming you about something that made absolutely no sense on a technical basis, while being a technical argument. Color of a bitmap does not affect performance, and to suggest so shows a great lack of technical aptitude.
And to answer your question : Only Apple knows why they removed the colors. No one but Apple staff sat on that meeting, and I doubt Apple staff will ever explain why.
And I think being "in your face" shows a great lack of respect and as caused me to walk out of stores. I think you should check out big surfaces nowadays or even car dealers. A lot have moved from pressure selling to a more casual attitude of letting the customer feel at home.
I have never said nor pretended that. Giving users the option of seeing or not seeing Ping pleases everyone. Those who want it, have it, those who don't, well don't.
I don't see how an option to remove something causes problems. Oh right, options are confusing and should be banned in favor of letting Apple dictate our entire experience right ?
And then I have to redo my entire music collection/playlists in some other software, not to mention it makes it hard to sync my iPhone. Or maybe I should get rid of that also ? And get rid of the Mac while I'm at it ? Now it's you who seems rather egotistical...
