Microsoft themselves had tons of trouble getting their customers to upgrade from Windows XP, but now maybe more people will finally take the plunge to the actually very good Windows 7 thanks to Apple and iCloud. Straight from the Apple press release: “Using iCloud with a PC requires Windows Vista or Windows 7; Outlook 2010 or 2007 is recommended for accessing contacts and calendars.” If you want to use all the new features of iOS 5 you’ll have to upgrade to an operating system less than 10 years old.
My work laptop was finally upgraded from WinXP to Win7 just a few months ago so I no longer have any computers running it but there are still plenty of office computers out there still chugging along on XP.
