Guys, which is the best operating system according to you? Not flavours/distributions/versions but actuall operating system! so guys, vote on!

Windows :

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).[1] Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced previously. At the 2004 IDC Directions conference, it was stated that Windows had approximately 90% of the client operating system market.[2] The most recent client version of Windows is Windows Vista; the most recent server version is Windows Server 2008. Vista's successor, Windows 7 (currently in public beta) is slated to be released in July 2009.

Mac OS X :

Mac OS X is a line of computer operating systems developed, marketed, and sold by Apple Inc. As of 2009, every new Macintosh computer ships pre-loaded with the latest version of the operating system (currently Mac OS X 10.5 "Leopard"). Mac OS X is the successor to the original or "classic" Mac OS, which had been Apple's primary operating system since 1984. Unlike its predecessors, Mac OS X is a Unix-based operating system, built on technologies developed at NeXT between the second half of the 1980s and Apple's purchase of the company in early 1996. Version 10.5, while running on Intel processors, is certified UNIX 03.

The first version released was Mac OS X Server 1.0 in 1999, and a desktop-oriented version, Mac OS X version 10.0 followed in March 2001. As of 2008, five more distinct "end-user" and "server" versions have been released, the latest being Mac OS X v10.5 in October 2007. Releases of Mac OS X are named after big cats; for example, Mac OS X v10.5 is usually referred to by Apple and users as "Leopard" (10.4 was referred to as Tiger, 10.3 as Panther, etc). The server edition, Mac OS X Server, is architecturally very similar to its desktop counterpart. However, it also includes several additional administration software tools to facilitate workgroup management or provide simplified access to common network services. These tools include a mail transfer agent, a Samba server, an LDAP server, a domain name server, and others. It is pre-loaded on Apple's Xserve server hardware, but can be run on most of Apple's computer models.

Apple also produces specialized versions of Mac OS X for use on three of its consumer devices; the iPhone OS for the iPhone, and the iPod touch, and an unnamed version for the Apple TV.

Linux :

Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel. Their development is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed by anyone under the terms of the GNU GPL and other free licenses.

Linux distributions are predominantly known for their use in servers, although they are installed on a wide variety of computer hardware, ranging from embedded devices and mobile phones to supercomputers, and their popularity as a desktop/laptop operating system has been growing lately due to the rise of netbooks and the Ubuntu distribution of the operating system.

The name "Linux" comes from the Linux kernel, originally written in 1991 by Linus Torvalds. The rest of the system, including utilities and libraries, usually comes from the GNU operating system announced in 1983 by Richard Stallman. The GNU contribution is the basis for the alternative name GNU/Linux.

DOS, short for "Disk Operating System", is a shorthand term for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 if one includes the partially DOS-based Microsoft Windows versions Windows 95, 98, and Me.

Related systems include MS-DOS, PC DOS, DR-DOS, FreeDOS, PTS-DOS, ROM-DOS, JM-OS, and several others.

In spite of the common usage, none of these systems were named simply "DOS" (a name given only to an unrelated IBM mainframe operating system in the 1960s). A number of unrelated, non-x86 microcomputer disk operating systems had "DOS" in their name, and are often referred to simply as "DOS" when discussing machines that use them (e.g. AmigaDOS, AMSDOS, ANDOS, Apple DOS, Atari DOS, Commodore DOS, CSI-DOS, ProDOS, and TRS-DOS). These were incompatible with DOS executables and the MS-DOS API.
