It’s the conversion to appliance. PCs just aren’t getting that much more exciting from 1 year to the next. This is both the hardware and software, there’s very little driving you to need the latest and greatest anymore, an 8 year old computer running 6 year old office apps will suffice for 99% of users these days. So there’s no reason to upgrade until it breaks, much like your microwave, no longer is your 4 year old computer a hunk of junk desperately needing replaced. This drops sales down, but there’s still plenty of buyers out there to support the market.
