Windows CE, PocketPC, PalmOS and so on were designed knowing that the user can only 
have 1 inputs enabling click for select (as well as double click, triple click and so 
on) and in some cases drag for dragging. Notice you can't right-click or mouse-over on 
such operating systems.

Windows for 'real' PCs was designed to have at least 4 inputs being the independant 
mouse move (which triggers mouseovers and the like), the left click for select (as 
well as the double/triple click), the right click for context and the left drag for 
dragging. Some programs also use the right drag, the 2 button click and the 2 button 
drag. It gets even more complicated for Linux.

Its more a case of what the OS was designed to use ... it'd probably be easier on a 
mac which was designed with only 1 mouse button where the only thing you'd miss is the 
independant mouse move (you'll still have your single button clicks and could emulate 
drags).
