Do you prefer reading hard print or from a ereader? How many books did you read last month?

when I read a book, I typically read soft cover, I just don't like hardcovers. I usually read Ebooks and Articles but I don't read fiction. I like to read many different things about science, design and engineering, including aviation, architecture and do-it-yourself/DIY. I don't keep track of how many I read but I do read a lot.
