In arguing for "super tablets" the author writes: PCs are expensive, prone to failure, easy to break and magnets for viruses and malware. After just a bit of use, many PCs are susceptible to constant freezes and crashes.

I don't see how a super tablet addresses any of that except perhaps cost. Ever drop a tablet? Have it fall into water? Ever see people using phones and tablets with shattered glass? I don't see them being less "breakable" than a PC, in fact much moreso because they are being moved around a lot more. They are also a lot more likely to be stolen, misplaced, or lost. And a tablet, especially one that runs MS Office, would not be any less of a target for malware than a PC, nor any more immune to it.
