The killer (or be killed) feature of that new Microsoft Surface for Windows RT is its keyboard. The tablet itself is a wonderful device. It's got a great body and a (seemingly) fast processor. But input is everything.
At the Surface launch yesterday, the auditorium was packed with the tech press, and lots of MacBook Airs, but there was nary an iPad to be seen. And that's because you can't really type on an iPad. If Microsoft has made something truly type-able, that's something we're going to see at events like this in the future.
