As a counter opinion, I think air-integration is a wonderful feature for us, the vast majority of plain, single-tank rec divers. However, I will agree that the WIRELESS air-integration is a major expense for something that isn't as reliable.
But I think a good hosed air-integrated computer actually makes more sense than an old-timey SPG, since you're going to have something you have to check hanging off an HP hose anyway, might as well go the simpler route and have everything there.
In Cozumel last November one member of our group had the analog SPG in his console flood, while some of us with our AI hosed consoles continued to work flawlessly. So those can fail, too. My point is just that the computers these days are reliable, so might as well go with an all-in-one.
Also, while I know one of these posters seemed to have a bad experience with the remaining air time calculations on his AI computer, in contrast I have found the "remaining safe time" gas-consumption-based calculations on my Sherwood Wisdom to be excellent and reliable, and will consistently bring me up right at or above my pre-programmed reserve, even with safety stops pre-calculated - of course, as long as you understand that the numbers mean "at that depth" and will go down or up as you descend or ascend, respectively.
Just a counterpoint to the old-timers here, many of whom would probably also recommend a "more reliable" brass sextant than a "fancy newfangled" GPS.
