Okay, last post - my wife's K3 finally arrived today, I wrapped it up and put a loving note with it.
She was extremely excited (easy way to wake an author out of bed - give them a Kindle

) but I have to admit I've been playing with it the most, very impressed - text to speech is spooky but the browser is quite nice. Tree of Life loaded with no problems, just a drag-and-drop in Ubuntu.
Many thanks - I guess it's now time for me to be released into the wilderness.
