Head injuries rise in MLB, talks of new helmet design on this week's The Hot Corner http://bit.ly/11DzCS #mlb #podcast

"how to build a PC that runs OS X, aka, a Hackintosh. So we asked our friend Colleen aka Digital Kitty, aka TWiT's Technical Project Manager to give us the step by step how to install a legal copy of OS X on a PC.

The heart of this build is an EFi-X V1 Boot Processing Unit and a full retail install version of OS X. US residents can purchase an EFi-X BPU from eXpressHD.com for $240. Cheap? No. But it does wonders with bootloading -and- allows to update OS X!

What's the big attraction to a Hackintosh? More build options than Apple gives you, and spending lots less on hardware."
