I used a Wisdom for awhile before I got fully into technical diving and went with a bascially DIR configuration. For a recreational diver there are pros and cons to air integration.
It puts all your eggs in one basket and the SPG feature adds an element of potential failure. 3 of my 4 wisdom failures were SPG related (I bought one of the first ones and the Wisdom, at the time, had a 3.5% failure rate, but the divers I dove with exceeded that as all five of us went through at least one failure - probably due to a combination of high alitude diving in alpine lakes where the computer may go from 100 degrees on the boat deck to 35 degrees at 100-150 ft in a couple minutes. Warranty support was however superb with on the spot in shop replacement.) If the SPG, fails you surface and are done diving. It is not the issue it was with early wisdoms but it does add some complexity that you don't have with a brass and glass SPG.
It will also display air time remaining or no deco time remaining, which ever is less and with a good SAC rate or large tanks, that number is almost always deco time remaining, which makes the air integration a bit pointless. The ability for the diver to select and lock one or the other would have been nice. For a new diver with a poor SAC and an AL 80, steel 72, etc, it has some utility, but it has to be taken with a grain of salt. For example jumping into cold water will cause a 200-300 psi pressure drop in the first few minutes which is pretty obvious. What is les obvious is swimming up through a sharp thermocline that will warm the air, increase the pressure and offset the gas you are breathing. The computer can't tell the difference, so it will give you an air time remaining number that is wildly optimistic until things stabilize and it recalculates. So you still need to use your head.
