They definitely did bet too heavily on netbooks, but that market has long since crashed. Chromebooks picked up a significant chunk of what was left in that segment. The more recent trend has been Intel's push for "ultrabooks", initially spurred by their desire to have a Wintel competitor to the MacBook Air. It hasn't been as disastrous as the netbook fad, but almost everything that superficially appears to be competition cuts corners in big ways and ends up being cheaper but a lot crappier and also basically unprofitable.
