I, myself am an Apple-nerd - I've been with Apple ever since the Newton came out. I see in the case of OS manufactures (e.g. Apple, Microsoft, Canonical, etc), that moving towards a unified mobile platform is crucial when we all seem to live more mobile based than desk based. It seems to be the way the markets are shifting. Just as Apple has shown that they will (read: might) not be bringing people back for another OSX release in 11.x, and moving towards a more iOS-based system, I think it's safe to assume that Microsoft is following the same trend. In the case of the Xbox 360, the box-like interface has proven somewhat popular. Although users have been forced to play along with the Xbox version, the Windows 7 Phone has been a big success for Microsoft.

I'm not a fan of this mobile transition, because it means that many of the desktop experiences I have may not exist on mobile platforms for a while. However, on the flip side, the mobile/desktop similarities and integration might prove worthy to the mass majority of not-so-tech savvy users out there in the market.

I found that after a while of using Mac OSX 10.7.x on my MacBook Pro, that the only thing I needed was Logic Pro. So I stuck it on an old '09 Mac Pro and soon after installed Debian on my MacBook Pro.

Looking back, I can attest that this has been one of the best decisions, though tech-savvy-ness is required to get it working and working with it. I don't know why I didn't switch earlier.

If you're looking into a more smooth transition or fun-flavored OS, Ubuntu works a bit better.
