I have to disagree. Tower PCs are currently only useful because our mobile PCs don't have the horse power. Mobile PCs will keep getting faster and smaller. So will tower PCs. There was a time they used to be a lot bigger and heavier. However, let us look at what made them that size : (1) hard drives - used to be huge and heavy. Seen SSDs of late? (2) CD-ROM drives - who needs them now when for half the space you get a memory card reader that takes media with more space? (3) power supplies - needed to be big and are probably what is keeping the tower PCs at their size, but there is now less need for large supplies with performance per watt going up. (4) graphics cards & CPUs - going to come full circle soon - these two will merge into one processor that uses less power than your average desktop CPU (5) motherboards - these are already really small. So, if you take these main components, the need for a full tower sized case actually is diminishing really rapidly. If you ask me, with tech like wireless HDMI, your tower pc is probably going to be confined to the attic or some unseen space very soon. We're very quickly reaching the point where smaller devices have enough computing power for most of our needs and as far as heavy lifting goes, I figure it is only a matter of time before every small little computing device at home is able to "lend a hand" and "help out" with all that computing. The very fact that PS3s are dominating the SETI distributed computing stats should say something. The PS3's cell processor is quite the beast. Are you trying to say that the PS4 is not going to be smaller and faster? What about the PS8? Do you thing you will be able to see it?
