The two companies I love/hate the most are Suunto and Garmin. These two companies are still alive because of their engineers. Not because of their sales, support, website, or customer relationship.
Garmin simply builds the best gps **hardware** devices (and I have to say, support them well in case of problem). And Suunto simply builds one of the best dive computer with inovative algorithm and user friendly display.
But none of these two company has developed software for the Mac. I guess that (statistically) 10% (or more) of their customers are not worth spending a few days developing user friendlier, Mac spirited software.
In addition, their PC software are just pieces of sloppy craps. Have you ever used Suunto Dive Manager (I use version 1.6 and 2.5 depending on what I have to do)? What's that user interface? Ever entered quotes in the name of a place, used foreign characters, imported/exported files from/to it, worked in different timezones? There were so many anoying bugs that I gave up repoting them (by the way, where should you report them?? Is there a software support at Suunto??).
The same runs for Garmin's Mapsource software that does not respect the minimum user interface conventions PC software use. And on their GPS devices, they only offer a pale copy of me-too features other manufacturers (like Tom-Tom or Magellan) have been offering for years. But still, despite of this weak user-interface software, they make a 12-antenna GPS-WAAS device with a precision that only few other manufacturers offer, and that's why I keep buying their devices.
Have you ever been on Garmin or Suunto's flash-based websites? Do you always find things fast and intuitively? They definitively do noty have the same "usability" test team working on their devices and on their websites. Do Garmin or Suunto have open forum? Noooo. They're too scare we publicly and openly complain about their products. (Fortunately, there are forum like this one!)
But be careful Garmin and Suunto: Other companies are catching up on technology (RGBM is no longer a Suunto exclusive), and are a lot less mean as fas as providing Mac-friendly software or open support through forums. I think that dispite your quality device, the next time, I will not buy one of yours. Not because of your device themselves, but because of your software computer skill. They're so bad, so poor in quality, that I really wonder how you still sell devices. I think you can thank your engineers who still build a very good hardware behind your sloppy computer software.
Many thanks to Mark Rosenstein for making Divelog for Mac, with Mac integration (iPhoto), and with NO support from Suunto.
