Microsoft is finally getting with the picture, almost. Aero glass won't work if your copy of Windows is not genuine (not that it matters, it'll be cracked anyway). This is the step in the right direction of offering value in a purchased product over a pirated one.
That's a very effective way to combat piracy, not by locking down your product and causing the people that actually purchase your products to feel like they are criminals. That's what the Windows activation does for me. It is also a privacy issue.
2014 is going to be a good year. More content, more streamlining. Be a part of history!
