I've got the Kindle version, and read it on both my Samsung Note 10.1 tablet and (converted onto) my Kobo. Both versions read fine, layout it solid except for the tables which go a little screwy. I find if it's not laying out correctly going back and forth on the pages can make it all snap into one place, no idea why.
One of the tables, possible the talents one, is pretty much unreadable though, so much data in one column. Imagine a spreadsheet where you make it really narrow, you have a column that's three words wide and 40 lines long

Convenient to have, but I did go and buy the paper version as well just for tables.
