Linspire Five-O is a full-featured Linux operating system which is intend ed for desktop use, mainly as an alternative to Windows XP. The company, which was formerly known as Lindows, has gotten a lot of press for including their OS with pre-bundled computers. Linspire's goal is to offer a complete OS which is as easy to use as Windows, but with the added performance and cost-effectiveness of Linux. Some long time Linux users have lodged complaints about the interface and the fact that this OS is designed for beginners but it has proven itself to be a great option.
