I wonder if it will work well as a "travel" computer? I could see leaving my laptop at home and taking this and a keyboard? Also it looks like it would be fabulous as an e-reader too, so I can drop Kindle and replace with keyboard in the bag.

That said I don't want to carry it or use it as my daily driver phone as I try not to use a phone in general...

It probably could. Wait till the 3rd generation where it will eventually end up growing in size such that unfolded it'll be equivalent in size to an 11" iPad.

I already remote into my Mac from my iPad using Mirage by Ethan Lipnik. Would be amazing being able to do that from an iPhone foldable!
