openSUSE 11.0 is based on the Linux kernel version 2.6.25 and provides a cornucopia of features. If you choose to download the full DVD, you can expect a whopping 4.5 GBs for the iso-format file. Other options include a Live CD and over the network. The good news is that you can use a BitTorrent client to get the iso file.
So what differentiates openSUSE from Novell's other distributions, namely SUSE Linux Enterprise Desktop (SLED) and SUSE Linux Enterprise Server (SLES)? To quote from the openSUSE FAQ:
"openSUSE, created and maintained by the openSUSE project, is a stable, integrated Linux operating system that includes the latest open source packages for desktop productivity, multimedia, Web-hosting, networking infrastructure and application development. It contains everything you need to get started with Linux and is ideal for individuals who wish to use Linux on their personal workstations or to drive their home networks."
