As we know Apple has released developer preview version of Mac OS X 10.7 Lion. It comes with lots of features. Only the registered user of Mac Developer Program will be able to download this version of Mac OS X 10.7 Lion. If you are not registered on Mac Developer Program then you will not be able to download it but you can see the new features of OS X 10.7 Lion in action. A couple of YouTube videos of Mac OS X 10.7 Lion running on MacBook Pro has been posted by the guys over at RazorianFly which shows the features of Mac OS X 10.7 Lion.
From these videos you can see new toys such as Finder and Launchpad. The iOS rubber-band affect is in full effect along with lists in Finder those are acting the same way they do in iPhone, iPod touch and iPad. The interface is also already very fluid. You can watch these videos embedded below.
