What a beautiful day. Not. To wit, this negative, frustrating review of Scientific Linux 7.1 64-bit edition with Gnome 3 desktop, covering live session, installation and use, including look & feel, network connectivity - Wireless (2.4Ghz and 5GHz), Bluetooth, Samba sharing but no printing, partitioning, package management & updates, applications, webcam, resource usage, and many problems related to hardware compatibility, lack of additional repositories, software and graphics drivers, poor multimedia support and missing codecs, font rendering, sluggish performance, customization issues, and more. There. http://www.dedoimedo.com/computers/scientific-linux-7-1.html Cheers, Mrk
