Last month Dell posted a website that in no uncertain terms claimed that Ubuntu was safer than Windows.
"Ubuntu is safer than Microsoft Windows," Dell wrote in its list of top ten things users should know about Ubuntu. "The vast majority of viruses and spyware written by hackers are not designed to target and attack Linux."
"Linux is used on computers of all sizes ranging from the biggest to the smallest," Dell said. "If you’re the kind of person who likes your computer to simply work, Ubuntu is right for you. It’s based on stable, secure, easy-to-use software that’s been around for a long time."
For this month, Dell has corrected itself to clarify that each OS is for different types of users with differing wants and needs. Let's see what Dell says this time (opens in new tab):
WHICH OPERATING SYSTEM SHOULD I CHOOSE ?UBUNTU is not a Microsoft Windows operating system - and is not compatible with Microsoft Office programs - so it's important you make the right choice:Choose WINDOWS if:You are already using WINDOWS programs (e.g. Microsoft Office, ITunes etc) and want to continue using themYou are familiar with WINDOWS and do not want to learn new programs for email, word processing etcYou are new to using computersChoose UBUNTU if:You do not plan to use Microsoft WINDOWSYou are interested in open source programming
So basically, people who use Windows or who have never used Windows should use Windows. You should only choose Ubuntu if you're into open source programming and so happen to require Dell's advice on which OS you want.
