I used my Cobalt for about 16 dives in Bonaire last Dec. My thoughts:
1.) Yeah, it's a console. But I get air-integrated without having to fool with a transmitter, and the built-in battery is rechargeable without being removed, so I don't have to open it up. And it lasts a good while.
2.) The interface is so easy to use it makes you want to slap your last dive computer's manufacturer. It can be used without messing with the manual for the most part (though I had to look up getting it to work with the computer for downloading dives). Adjusting to local time zone, nitrox mix, etc... could bring tears to the eyes after working with regular dive computers (compare adjusting settings in an iPhone vs. a digital wrist watch to get some idea). This is a huge benefit.
3.) I could've bought an Oceanic ProPlus 2.1 and got most of the same 'functionality' in terms of what the computer would do (e.g.: monitor depth, air remaining & theoretical tissue nitrogen loading, log dives for download later, etc...), but no way would it have been equivalent.
Are you technically minded? Does grappling with manuals of questionable writing quality on complex, dry technical writing bother you? If you leave how to do a few things with it, will you remember how to operate it after months of inactivity? Would you pay significantly more for something 'slick & easy.'
Usability is a feature.
