Well you can be as rude as you like about my opinions, but what has Tabs in a browser got to do with Microsoft. That's just obfuscating the issue and irrelevent here.
Fact is that the old way of doing it was clunkier in that it took longer, with more taps of the screen to switch from one loaded page to another. Also, tabs is THE standard way of doing this in OSX. So for these reasons (i.e. it's more convenient, quicker and the standard modus operandi), the current implementation is the BETTER way of doing it.
Anyone may personnally have some preverted reason why they like the old method, but that doesn't in any way, shape or form, mean it is better. In fact it rather smacks of just refusing to accept change, even when that change represents an improvement if only you'd stop bleating on about how terrible it now is.
In any case, don't berate Apple for being in some way 'so arrogant' in making the change. They saw it as a better way to do it and so they implemented it. That's what developers do, they have to. Some users will like the change, some won't and as the developer, you just have to live with that. You CANNOT please all of the people all of the time.
Me, I just think people should stop wasting time moaning and wringing their hands in despair over this, what is after all, a very minor and trivial change. Get used to it. It is NOT going to be changing back. Move on with your life and just enjoy using these fantastic toys we now all get to play with.
