although I am somewhat a new user, I am very happy with the computer and find it very user friendly and here is a couple of points that I see.
1. The new diver has the ability to grow with the computer and not need a new one as they progress and as an old diver doesn't "need" much else.
2. The ability with the HP Link to monitor your tank in OC or constant PPO2 in CCR is a treat.
3. The software for Dive logging is straight forward (now that it's working on my mac)
4. The color screen is awesome
5. All the PINs are BS and a pain in the

and expensive
