Wheel counters are good when you are designing the system solely for your robot chassis, but when you want it to be easily accessible to hundreds of other possible variations you're going to want to go purely inertial. Then you can have fun accounting for drift.

I suppose it all depends on the level of accuracy you're going for. We made a very simple one in a night (basically euler timestepping for approximation) that was accurate for about 5 seconds, which was all we wanted it for: Just to judge how far the robot had gone and if it got hit. One that accurately tells you where you are after long periods of jostling on inertia alone is pretty intense, that's way beyond what I was talking about. It's still a good project even if I underestimated the undertaking.
