It works fine, its just more annoying seeing 1-2 lines at a time. With iDrive you can see a lot more at once.
But if you're trying to convince yourself to "settle" for a car without iDrive, then don't. You'll regret not holding out for one later. If you never considered or wanted iDrive to begin with then it's a different story, but it sounds like you were already set on getting it.
