I love this setup. After the new ARM chromebook came out I got all excited and looked about for a way to dual boot a full OS on my old series 5. It turns out it's easy now (http://chromeos-cr48.blogspot.co.uk/2012/04/chrubuntu-1204-n...) There is a lot of pleasure in using such a small machine.
I am definitely looking forward to an e-ink laptop. As I get older my eyes grow more weary, but the e-ink display on my kindle is a joy to look at.
