Oprah Winfrey has been vocal about her love for Microsoft’s new Surface tablet.  Even claiming that it was one of her favorite things.

But that didn’t stop the chat show queen sending a tweet claiming she’d bought 12 as Christmas gifts – via the Twitter app on her iPad.

Microsoft has spent $1.5billion and enlisted a string of celebrities to help market their latest gadget – a rival to Apple’s offering.

Gwen Stefani, Jessica Alba and Oprah have all endorsed Windows 8 and its mobile phone equivalent, with the latter putting the Surface on her list of 48 favourite things, TechCrunch reported.

However, the latest PR gaffe seems to suggest that however much Oprah promotes Microsoft’s latest tech offering, she likes Apple’s version even more.

According to TechCrunch, there is not an official Twitter app for the Microsoft Surface.  However, if Oprah had not been able to track down one of the several third-party Twitter apps that have been published for the Surface, she could have still accessed the Twitter website to send her tweet.

Instead, it appears she used Twitter’s official app on the iPad to send the tweet.
