If you're fed up of Windows then you can make the switch to Linux today; I'm dual booting Windows 7 and Linux Mint Debian Edition, and when I upgrade in the summer I'm going to take the plunge and only install LMDE.
ARM isn't going to replace Intel at the high end anytime soon though (read: ever), if anything Silvermont and Airmont are going to eat into ARM's market share in the lower end of the market.
Linux doesn't have the software support I need just yet, because there isn't a distro with proper commercial backing that supports the user as much as Windows does. We need to move on from this horrible old OS, but I'm not going to until I get the game support and general software support I need. Thankfully, good old Gabe is starting to make a change, and the market share is quickly shifting due to W8 and tablets.
ARM aren't replacing Intel because they aren't trying to; If they brought out desktop processors, companies like Apple would jump straight to them (They already are in the mobile market - Mac Air) and the lower licensing fees and such would quickly bring the rest of the market too. No matter how hard Intel try, they're never going to make the same mark that ARM has in that sector. Yes, they have lots of money, yes they spend 10 bajillion pounds on R&D, but their fundamental failure in the mobile market is them being late to the show and the fact they're using their old decrepid architecture that sucks power like nobody's business because it's inefficient. It took Intel this long to make a decent powered SoC within the right power bracket. The only reason they managed it is because they have the world in money to spend.
x86 dates back many, many years and has only been added to, not refined. The ARM architecture is and always has been more efficient, and I firmly believe if ARM decided to make socket processor designs as well as their hot cake SoCs that they'd make a big mark in the desktop market too, particularly due to price.
I'm not saying ARM ever will do this, but by God I think they should.
That comment is stupid they do not change sockets for no reason.
Give me a good reason why Intel change sockets constantly. They never used to, never needed to and neither do AMD. It's a shameless act to get people to buy new mobos. They changed 5 contacts for the new processors!! 1150, mirite? They could have easily stayed with the old layout.
If you're really trying to defend Intel for this then you clearly are just a fanboy.
