For anyone that doesn't know this, you can connect USB keyboard to the iPad Camera Connection kit. It works with most keyboards, including mechanical ones.
Or just use a bluetooth keyboard and forget all the dongle and wire mess.
But don't forget to charge the keyboard ;)
If you see a stylus, you know (there's a video with whiskey-smooth voiceover coming)
Hmm ... call me stupid but ipad + keyboard << macbook . What is the point?
I'd guess the option to use the device without a keyboard if you wanted to.
