Pbooks for non fiction mostly. Like cooking books in strange languages that are not available as ebooks. There is this new Scandinavian cooking that is in fashion, for good reasons, btw.
I like to read the printed version when I have to read fast, like when we were discussing the Master and Marguerite in one of the bookclubs and I was behind with the schedule. The printed version lets me jump ahead more easily to follow a particular thread. Temporarily.
Creative reading 
Cookbooks in eform are very handy in the kitchen. Either I keep them up on the ipad, or, better, I calibre them in rtf and put the recipes in Evernote, for easier reference. I even got a fancy book holder for the kitchen (that works marvels with the ipad also), with much myrth of the two primitive (in the sense of cooking) she persons that share my cooking, and enjoy it. You should see how they feed themselves when I am away on a trip.
