I just hope this won't clutter the interface on most Mac programs. (tho I guess it will.)
One button makes for simple interface. Like cheetah, for example. (I hope cheetah won't change its interface, btw.)
Actually, one-button or two-button mice make the interface more complex for 3D apps, because togglebuttons (or key combinations in the keyboard) are needed to define the current mouse action (panning/zooming/rotating). In the world of UNIX workstations, where 3-button mice were standard (shipped with every new workstation), many applications had a fully usable 3D view without any navigation-mode togglebutton (which saved GUI space for really necessary buttons, or for having a bigger 3D view), and you could fully navigate in 3D with just one hand in the mouse, and the other hand free for drinking Coke.
Anyway, in my opinion, one-button mice are very comfortable for most desktop applications (except 3D and games). Being new to the Mac, I've fallen in love with its one-button mouse, I really like it. But for 3D, or for playing games, it's not very functional, as you need to either push togglebuttons, or use the keyboard, and that's not comfortable at all.
Btw, the MightyMouse seems to have been very well designed to behave (and look) as a standard one-button mouse unless the user wants it to use it as multibutton.
Although, I've my doubts, because given its price there're some points that I don't see clear:
1-As told in AppleInsider... how do you clean the scrollball when it's dirty? Honestly, I wouldn't care about this if it was a $20 mouse, but at $50 durability is an important issue.
2-Some users feel uncomfortable and returned it to the shop. This means that you can't buy it without trying it first, and that's not a good symptom.
3-Tell me stupid, but I really like the transparent plastic of my current Apple mouse, and I guess I'll miss it with this new mouse.
