The latest numbers for the PC industry aren't good.  Gartner
says sales were down 11% in the second quarter. This marks the
fifth straight quarter of declining annual sales, notes Alex
Cocotas of BI Intelligence.  The traditional PC industry is
contracting because of the iPad.  Apple's iPad is a good-enough
substitute for PCs. Instead of buying new, expensive PCs, people
are holding onto their current computer and supplementing them
with iPads, and other tablets.  Microsoft's Windows 8 was
supposed to fend off the rise of tablet computing. So far, it
looks like it hasn't worked.  chart of the day pc industry
