C'mon, they haven't stopped buying computers. The market has just divided in two:
--Power users who buy desktops and laptops because they need options, settings, the ability to install freeware and do funky things.
--Casual users who just want the darn thing to get them online without a lot of fuss.
It's very easy to see these two groups aren't that likely to want *everything* to sync. The tablet/phone people will likely gravitate toward that, but the desktop and laptop users are still going to want choices and control.
