I don’t agree with the point on convergence. It seems clear to me that Apple is not turning OS X into iOS. It’s still very much a WIMP interface best suited for keyboard and mouse. Windows 8 is a good example of PC/tablet convergence, and however much you like or dislike that approach, it’s the opposite of what Apple is doing.

On some other points I do agree, like the gluing down and lack of expandability/repairability.
