I have the Cobra, a hose-connected air-integrated computer. Mine was the "Pro Pack" (ok, yeah, whatever) which includes all the optional stuff like a very nice integrated compass, quick release, and computer download cable w/ software.
This is one great computer for recreational diving, especially for a newer diver or the occasional diver. It shows you everything you need to see, when you need to see it. For example, since it is air integrated and calculates your air usage on the fly -- in addition to your NDL -- it automatically displays the shorter of remaining air time or NDL time.
Like all of the Suuntos except the Gekko, it is PC downloadable, has a simulation mode in addition to the planning mode, and a nice backlight. The download cables still use serial ports
but serial-to-usb connectors work.
Like any Suunto, its conservative but mostly for dive plan mistakes such as fast ascents, reverse profiles, too short surface intervals. It automatically shows you your safety stops, and it has an easy to use ascent rate monitor with a *safe* rate which not all computers do.
IMO, ascents are the one place where a wrist computer on your right hand would be a bit easier, but that takes all of about one or two ascents to get used to. Other than that, if you are already used to holding a console in your left hand you will immediate like this computer, and the integrated compass is especially usable, not just an afterthought.
The optional quick release is technically YAFP (yet another failure point) but it lets you take the computer with you without dragging around your whole reg setup like other consoles. You can buy the Cobra either way, going without the quick release will definitely save some cash, but I'd say to definitely get the integrated compass.
OTOH, if you don't like consoles or aren't used to how you have to take care of one (either holding it, keeping it somehow clipped off, or otherwise off reefs, rocks, silt, docks, boat decks, etc. like we all should anyway) then this probably wouldn't make a good choice, since it is expensive as all getout.
