Garmin's big enough to do pretty much whatever they please with their product designs & software to run 'em.
Apple's got the same ethic, take it or leave it.
I hesitated before buying a Varia last spring, again when I bought an Edge 840 a few weeks later. The Varia does what I expected, the Edge is taking more time than I expected it would for me to figure out exactly how to do what I want it to do for me.
Been an Apple user since 1993, made a decent living using their machines for producing graphics for sales centers. They're capable of doing a lot more than I need 'em to do for me, but as they make it pretty simple and reliable to get things done that I need to get done, I've stuck with 'em.
