Another day, another new provocative ad from Microsoft. Taking jabs at Apple and iPad in the hopes to swing people to Windows 8 ultrabooks and tablets, the new ad opposes the Lenovo Yoga – an awesome and flexible ultrabook that we had the pleasure of testing not too long ago, against Apple’s iPad. Which is like comparing oranges and, err, apples, but whatever. It’s advertising. According to Microsoft, you will have a very tough time multitasking on an iPad when at a lecture. With the Yoga, you can quickly turn the tablet into a full-fledged ultrabook and start taking notes.
