I've seen all the Longhorn previews, but never understood why people are amazed. I figured, "Hey, they're used to XP, so that's why it looks good to them." Yet Mac OS X'ers are saying it's amazing...
I don't get it. I've seen them over and over, and I don't see anything very special. I see a little bit of flashiness, but it ultimately is just using up processor power for inefficient eye candy. I like eye candy, but it's gotta have a concrete functionality to it. Expose is functional eye candy; works great, and looks great. Having stuff seem to gravitate out of one window and get "sucked" into another is neat-looking, but ultimately of little value; in the end, it's a waste of processor power and time for the power user.
Also, I dislike eye candy that takes up time. If the eye candy is going to slow me down in order to show itself to me, I don't really want it. At least, not as an integral or basic part of my OS. Kind of like the bouncing icons in Ubuntu Beryl ... it looked cool, but ultimately useless and a waste of time. Now the rotating cube for viewing multiple desktops, that has some value (not sure how much it has if you can't fit all your multiple desktops onto the cube's surface).
It seems that Microsoft still isn't aiming to make their OS more beautiful, mainly they're trying to make it flashy. Vista is a step up from XP's drab and business-like look. But still, OS X is a dozen steps up from Vista. I am not a Mac fan boy by any means, and I regularly run Vista on my iMac (mainly for games, but also to try it out and see how it feels). However, OS X is just prettier and more functional.
Look at this way... an OS's exterior look is like a woman's beauty, and it's functionality is like a woman's personality. Beauty without functionality is ultimately of no lasting value; it gets old, and you yearn for something significant and meaningful. A great personality without beauty is much better than beauty without personality, but more to be desired is to have BOTH the beauty and the personality. OS X has it. I'm in love
Not really love, but you get the idea.
Vista was a huge step up in personality, but I still just don't feel as efficient using it. It could partially be my workflow style, but it doesn't seem as functional as OS X. Now granted, I have some qualms about Leopard too (pointlessly reflective Dock, translucency, etc).
