I like the idea of pavers(and its not my $$$) but I have experience with small (8" x 8") pavers on my walkway. One or two can tend to frost heave and at times I will catch my foot on one that's lifted slightly. They are well bedded in gravel then sand but still a couple can tend to heave slightly - I tend to shuffle at times too.
Translate this to your driveway and the only problem I can see is catching either your front blade or rear blade as you plow snow - if there were any frost heaving. I like the patterns you would be able to create with pavers, its easy to repair any that might become damaged and generally speaking they should last a lifetime.
