A second reason for the PC sales slow down, beyond iPads
So PCs are losing marketshare to Ipads. This is documented. But this CNN commenter makes a good point about a secondary disincentive to PC buying.
GoAwayObama: The problem with PC sales is there hasnt been any real speed increases in CPU’s in years. I just got a brand new top of the line core i7. It has 8 cores, but its really not any faster than the 5 yr old computer it replaced.
VoteObama012: Nice post GoAwayObama! I completely agree with you. The pc is now a commodity like a tv, toaster, or microwave.
