I don't think most of the people posting in this thread know much about Samsung's products, and didn't even watch the keynote. They see a few headlines and conclude Samsung is just copying Apple when in fact nothing is farther from the truth.  In the demo they showed a video playing on the external display while he was doing something completely different on the Note, so clearly its not screen mirroring.  Beyond that, DEX is a really cool technology that truly lets a lot of people use their phone as a full function computer with mouse, keyboard, etc..  It used to require an adapter box which appears to now be integrated into the device.  What wasn't clear is if supports keyboards and mice.

I think you are pushing it a bit as the average person will get no where near 6 years of usage on a phone.  Just wear and tear and the battery aging will defeat that dream.
