But you can tab through windows, thats my entire point, you havent taken the time to learn these things. I did read all your previous posts, my point was that surely if you are spending that much money and purchasing a system you have not used before, you would try it out beforehand, and you would have noticed that the home and end keys are not on separate buttons. One of the things that attracted me to the mbp was the keyboard layout on a mac, but I certainly wouldn't have bought it without giving it a test drive first.
I fail to see how clicking start, programs and then launching an application is any easier than just clicking on an icon in the dock or in the applications folder. Just the way that the files are stored are easier for a novice and much easier to find than on windows.
I just think it is far too early to be making the complaints you are making as you havent given it a fair chance, and most of the problems you have with it you should have checked out before you bought it.
I am still getting used to my Mac and so far loving every minute of it, but that is only because I am approaching it with an open mind and not expecting it to be any more than it is, which is just an OS that allows me to open and install the programs I want to use with minimum fuss. The advantage is, it looks and works good, but only if you give it a chance.
