Slashdot videos: Now with more Slashdot!
When talking CPUs you can't get them much faster or more feature-rich than Xeon. Intel has, simply put, pushed far ahead of any other competitor on the market, and they don't seem to be slowing down. But the price will match that to be sure, which is why AMD still has a market share.
They don't actually block content. If you use your ISP provided DNS service then lookup requests for certain domain names will be hijacked, and redirect to a "This page done bad" website.
As the article states, actually blocking content requires snooping on content and that's not just expensive, it's legality is questionable. As such, if you want to torrent and whatnot, you are still free to switch to a public, unfiltered DNS service á la Google or OpenDNS.
