It’s to be expected.
Blame Tablets for Everything (including Slumping HDD Sales) – HotHardware
The question is how much this is currently an early adopter game, as some people seem to buy anything for no other reason than that it’s a new type of gadget, but tablets will surely replace more casual uses of laptops, and longer term will replace or merge with e-readers.
The problem overall is that people see the iPad as a template. Forget that and instead think lighter devices (most current tablets are not light) and more adapted to being used as reading devices. I truly hope innovation will continue.
Desktop PCs and netbooks are already labeled for extinction, but I’m less concerned about laptops for now.
It’s no question that tablets are disruptive.
