Apple iTunes Store has the Essential Anatomy 5 App by 3D 4 Medical for iOS on sale for $0.99 (96% off the regular price of $24.99). This is a fantastic anatomy application and I use it regularly on the iPad. I purchased this app way back for $24.99 and it is STILL worth every penny.
This is what I would call a NO BRAINER deal. Grab it while you can!!!
