Sun calls its Java Desktop System "the first viable Microsoft Windows alternative," but it’s apparently much more than that. One crew member trying out Sun’s bootable JDS evaluation disc made an intriguing discovery: You can insert the Linux-based disc into any NTFS (NT file system), boot up, and bypass Windows security to gain access to all the files on the hard drive (kids, please don’t try this at home). It’s an open source OS and an anti-Microsoft hacking tool all in one -- what more could a geek want?
