I guess Jobs was wrong when it came to Nokia they were 4 years behind not 3. My first response was wow someone put an ugly cover on their iPhone, then I saw the Nokia logo and started to laugh. At least MS had the balls to try something other than a cheap UI knockoff.
I don't know why you've been down voted to oblivion, but have an up vote. :)
This thing is not even close to Android or WP7, let alone iOS. Swiping is a feature now? Really? The basis of every phone since 2007 is a great new feature?
"Full Screen Mode" is not really about full screen. It is an attempt to simplify the concept of virtual desktops, making it more intuitable to ordinary humans, while also putting applications or tasks into a linear arrangement so that they may be navigated more easily with multitouch gestures (task switching).
I have Lion (dev preview) and it's very useful, but for browsers there were always ways to go fullscreen (Firefox, Chrome, etc), even my Aquamacs on Snow Leopard. Having it for everyone is even better.
OSX Lion's fullscreen mode emphatically "is" unique. I haven't seen any other desktop OS that has a system-wide fullscreen (not maximize) button and nobody else is even in the game when it comes to bringing multitouch gestures to the desktop. The gestures are important - the entire point of Lion's fullscreen idiom is to bring the intuitiveness and immersion of post-pc apps to the desktop.
Probably for the tone of my post. The phone does look very nicely done, but that first shot with the little grid of brightly colored icons is an almost exact dup of every iPhone picture I have ever seen. They even use the exact same color and icons for phone and messages. Seriously open up Apple's and Nokia's pages side by side They really look like the same family of devices.
