Apple Thoughts: Which Shift Key Do You Primarily Use?

After reading Chris' post about what makes a perfect keyboard, it got me thinking about Shift keys. In Canada, many laptop brands ship their laptops with a French/English keyboard, and when they do, the left shift key is cut in half to make room for an extra French-language key. The net result is that any touch typist trying to use that keyboard, if they're not accustomed to it, will constantly be missing the left shift key. I'm one of those people, and I flat-out refuse to purchase any laptop that doesn't have a full-sized shift key. That means no HP laptops for me - every single one of their consumer laptops sold in Canada have the shrunken left keyboard; it's one of the main reasons I tend to go for Dell laptops. I'm pleased that Apple allows you to choose what kind of keyboard you want on your laptop and wished more companies offered users that choice. If I primarily used the right shift key, however, I wouldn't have my choices curtailed.

What about you? Which shift key do you primarily use? I use the left shift key 100% of the time - never even touching the right-hand shift key.
