What would you call an optional, detachable keyboard if not a "feature"? It also doesn't "need" a trackpad.
Your understanding of the quoted words differ from my own.
When I hear comparisons to a laptop, and someone mentions "you can detach the keyboard" it doesn't strike me (personally) as a feature, as I have never found myself wanting to do that on my laptop.
I have... I thought a keyboard would be nice to use with the ipad until I experience the frustration of having to reach up to touch the screen. Made using the keyboard more cumbersome than it was worth. A touch pad for those circumstances would have been ideal.
So we have gathered some anecdotal evidence here, I guess it depends on how you work. I tend to use it on a pretty low table with the iPad facing up which I have no problems with.
