Yesterday a Windows 8 tablet vs. iPad showed up highlighting some of the difference between Apple’s tablet and the Microsoft slate. In that video the Windows makers used Siri’s voice to point out its weak points. This time around, it’s a classier and much simpler ad, highlighting similar things: lack of Office apps, multitasking and SD card reader. It’s a compelling argument, perhaps Apple should revive the old Mac vs. PC ads, but with iPad vs. Surface, and maybe point out the lack of other great apps on Windows 8.
