Hey,
I am just takeing a big guess on this post. As Adobe is now part of the Macromedia family, I am going to guess that there web site was done in Dream Weaver and also parts of it may have been done in photo shop like the pictures and things like that. They also may have used some Flash work on it as well. But, over all for the web site I am going to guess and say that it was made with Dream Weaver and PhotoShop. Also, maybe a little bite of Flash was added to may be.
As, for the
http://store.apple.com I am going to say that most likely the same. Dream Weaver is a tool that almost all the big companeys uses. I am a mac user and I use the Macromedia Family and also the Adobe Family sofeweare for my web sites and the other web sites that I make and help other people make as well. That would be my guess for
www.youtube.com also.
Again, this is all a guess as I did look at the web sites and I tryed to guess on it. I am just trying to relearn every thing that I did know at one time.
Also, you maybe able to see the code and see what it says. It may have some comments in it as well.
So I hope that this helps you in some way. Sorry that I did know any more than that.
