Let me sour up your day. Here's an extremely negative review of Scientific Linux 7 64-bit edition with the Gnome desktop, covering live session, installation in a quad-boot setup and a mostly unsuccessful attempt at daily use, including Wireless, Samba sharing, look & feel, customization, partitioning, applications, multimedia playback - MP3 & Flash, firewall, stability, system resources, tons of problems like horrible Gnome 3 components, lack of usability, missing functionality, crippled software management, lack of ability to change and tweak the system and install programs, and more. Enjoy, not. http://www.dedoimedo.com/computers/scientific-linux-7.html Cheers, Mrk
