I’de go with actual for reference purposes in the future and I like to have books in my satchel at all times for any free time that pops up. E-book means having to be in front of a computer?? no thnaks.
If there’s no significant curriculum changes between 2010 and 2011, then why not just use the 2010 hard copies and print off the stuff that’s changed from the ebook?
maybe I would like to choose paper one…coz lots of ppl told me that it’s useful to read level II curriculum instead of Notes 
I signed up for both - figured I could study when I’m on business trips with the ebooks rather than having to lug around the hard copies… But will definitely be a hard copy person when I’m at home.
