As long as we're pleasantly drifting... while I love my Macs and would never return to Windows, one thing I don't love about Mac is the uncomfortable use of the Command key for these common functions while writing. It can be painful on the thumb -- especially when you have to do a lot of pasting.
It's not at all ergonomic to bend your thumb in while pressing out your pointer out for Cmd-V. In contrast, using your pinky (which you already use for all the other nearby keys) for these 3 Control combos places your pointer in a very natural position for X, C or V (with your middle finger also good for X). Ctrl-V is very close to the hand's natural finger spread and typing position. I suppose if one has tiny hands, this may not be true. But then, things are naturally designed for average users.
Place your thumb on Cmd, and pointer on V. That's not a natural or comfortable hand position. Now put your pinky on Ctrl and pointer on V. That's very close to a relaxed hand position, with C being pretty much dead-on, splitting the difference between the 3 shortcut keys for maximum comfort.
That said, Cmd isn't so uncomfortable when you're not hitting the combos many times in a row.
Just as a historical aside, the Cmd key was more comfortably placed on the original Mac (which I had back then), as it was both longer and more to the left. That was when Apple took Xerox PARC's dedicated Copy/Move/Delete keys, and made them the 2-key Copy/Cut/Delete combos.
As for keyboard shortcuts in general: there's not really a notable difference between Mac and Windows systems in terms of ease or consistency. Never had a problem with either. Software from third-party companies sometimes uses different shortcut keys for certain functions (on both OS's), but that's almost never true for the common standard shortcuts.
As for toolbars: they're on Mac apps (with popups) too. All those years I used Windows, I never had to zoom in and out due to toolbars taking up real estate, and never heard of that. Pretty much the same real estate on Macs. Pages, for example, has two standard rows of toolbars, just like Word. (Word recently added the Ribbon, which places useful contextual power-user tools at your fingertips if you want them, but it's optional.) On both Windows and Mac OS's, you can choose to hide or show (or even add) toolbars in most apps.
Bottome line: different people prefer working different ways. Both Mac and Windows OS's offer plenty of options for users to work how they wish. Sometimes doing everything by keyboard shortcut is preferable. Sometimes people like to take their hands off the keyboard and just use the mouse for some things. Some people like a combo. Whatever works for an individual for a given task, more power to 'em. No one "right" way.
