"“Now you have the option to acquire Xandros Desktop offerings together with Microsoft patent assurance. This assurance enables you to use Xandros Desktop software with confidence. This program is available for $50. Learn more by reading Microsoft’s covenant.” “How much does the same thing cost for SLED?” This even links to Microsoft’s Web site. Nice, eh? What a pleasant experience purchasing GNU/Linux from Xandros. This also applies to Linspire, which Xandros bought. They sell Debian with a Microsoft licence for imaginary software patents."
