Our home media PC is getting a little long in the tooth. It’s always been a bit of a problem because we bought a horizontal case that would look pretty in our media room, rather than one optimized for holding PC hardware. Right now, the machine is just about three years old, hasn’t had a Windows reinstall in all that time, and has developed its own set of quirks. It’s getting near that time. It’s getting near that time when either a Windows reinstall is necessary, or its general crotchetiness will give us an excuse to build a spiffy, new machine. And that has had me thinking about whether we’ll just put our trusty copy of 64-bit Windows 7 on it, or hold out for Windows 8. That has had me thinking about whether I even want to run Windows 8, and that got me thinking about what it would take to make Windows 8 a real, acknowledged, indisputable success in the marketplace.
