PC are going away in a way
People care more for Low Power / Portable Devices to do Cloud Computing.
What I will like to see is the way of Home Servers like a small scale Mainframe. That way all you need in your house is a small portal type device. A Tablet, Netbook, or even a Phone can access it. Another thing that will be awesome if you are good enough is to have your e-mail delivered there too. You are in control of your data or outsource it like Gmail, Yahoo, AOL, Hot Mail and such.
I am thinking on getting a commercial line, but now my ISP let me up load almost 3 MBS, so will see how well it works. As is right now, Netflix at my house is moving close to 4 MBS so, might work just as fast. If I can register the domain it would be even nicer, but as is right now, I have to use the IP Address of my Router with port forwarding.
Either way, the PC market is shrinking.
BTW, I have not bought a PC in ages and I made my last PC back in 2005/2006. Still up and running like champ (AMD64 3000+).
