The last time I downloaded VitalCrap to my computer post-graduation (late 2007), they told me I couldn't purchase updated versions of individual books. Now I'm browsing their "bookstore" on the website and it appears I can add books to what I have from when I graduated (2004) but I'd have to pay full price for it. No thank you, I'd rather pay that price and buy the textbook for my physical bookshelf. My patients might think I'm smart if they see real books on my bookshelf. Overall, I don't think it was a good investment of the $5K or whatever I was forced to pay during my 4 years of dental school. I have used it since graduation, but I would have been fine had I just owned paper copies of the books I consulted.
