I think people are pissed off with PCs.

They bought a windows machine for what to them is a lot of money (more than a iPad), it didn't last long before it slow and it's got extra toolbars and all sorts of rubbish. What's worse is that this happened last time they bought a PC and the time before and the time before that. They are not going to add a SSD because that's not how they think + they don't how + it's throwing good money after bad + they are dubious of the benefits.

The iPad in contrast exceeded expectations and in the year or two they've had it they had a better experience. They can't get excited about a another windows machine because it's expensive, more of the same and not worth it really.
