Microsoft Chairman Bill Gates thinks Apple’s iPad is "frustrating" to use because it lacks a physical keyboard and doesn't run Office. The Surface, he says, brings the "portability of the tablet but the richness of the PC" to mobile productivity.
Being a Google Apps fan, I'm obviously biased and not exactly the right guy to comment on the Office part of Bill's comment.
Now, I'm underestimating the real world outside the Apple bubble and obviously there are heavy Office users out there who agree with Gates on Office for iPad. Regardless, you'd think Microsoft's co-founder should know that any Bluetooth keyboard works with iPads.
On top of that, a bunch of iPad cases incorporate physical keys like NIBIQÜ's and Logitech's Surface-like iPad cases, the latter featuring physical keys seamlessly fused into its interior fabric. Go past the fold for the full quote and video evidence...
