Michael Geist explains in plain English why there is no reason to rent (you’re not purchasing it anyway) Microsoft Vista:
Even after installation, the legal agreement grants Microsoft the right to revalidate the software or to require users to reactivate it should they make changes to their computer components. In addition, it sets significant limits on the ability to copy or transfer the software, prohibiting anything more than a single backup copy and setting strict limits on transferring the software to different devices or users.
Vista also incorporates Windows Defender, an anti-virus program that actively scans computers for “spyware, adware, and other potentially unwanted software.” The agreement does not define any of these terms, leaving it to Microsoft to determine what constitutes unwanted software. Once operational, the agreement warns that Windows Defender will, by default, automatically remove software rated “high” or “severe,”even though that may result in other software ceasing to work or mistakenly result in the removal of software that is not unwanted.
Given that most applications are available on the web (e.g. GoogleDocuments, Gliffy, Gmail …) and that Apple or Linux give you an excellent desktop, is there any reason to support this monopoly? Not for me.
