After all the heat Psystar took in the blogosphere for its erstwhile Macintosh clone -- a commodity box that can run OS X -- many said the company was either a sham or about to fade quickly away. Well, in recent days, the company has begun offering its own Mac updates for Psystar Hackintosh users, pledges more surprises in the future and is also offering a pretty nice $299 computer called the OpenLite that runs many versions of Linux and has pretty nice specs for the price. While they used to preinstall only Ubuntu, the most recent announcement has them also willing to install CentOS and Fedora for those who want them.
