Shearwater compasses: it's great that a compass exists and is there should you need it.
This is where the Nerd absolutely comes into its own, especially if you've "fallen off the wreck" and are doing a long circuit to find it again. It's particularly great when scootering around a barren bottom to find the wreck or look for other artefacts.
As for AI. It's great on the rebreather where gas pressures are very much of secondary, even tertiary, importance. Using the transmitters on a rebreather really cleans up your front getting rid of two long hoses and SPGs.
When diving OC, backmount or sidemount, it's just as easy to use a normal SPG. Certainly the Shearwater user interface display of pressures is awkward: either use the 'twin' display in the centre row, or loose the entire bottom row to display pressure (this includes the TTS and ceiling which are far more important than pressures).
Anyway, each to ones own. I still drive a manual transmission car and hate automatics. I absolutely despise all the other "safety features" which adds complexity to something you should be naturally doing (ding ding ding as you move into the next lane without indicating; ding ding ding "you look tired"; ding ding ding you're too close to the car in front as you get ready for the overtaking manoeuvrer...). Tech doesn't always add benefits; it frequently detracts and distracts, worse still it can fail when you're really relying on it.
