I'm concerned about this move. As long as you can continue to install things outside of the sandbox and Mac App Store, I'm happy, but there's a massive flag going up in my head over this, I'm really not sure Apple would be able to resist the urge to integrate the locked down nature of iOS into OSX. This concerns me to the point where I'm now rethinking 3 MBP purchases as I'll be stuck with them for 4 years at work, and I don't know what OSX will be like in 4 years time.
