That's kind of sad. If you hadn't been on the brakes when you hit the pothole, you might have just kept on driving.
Of course, I hit a similar pothole @ 70mph, and it broke the muffler pipe, the muffler, and damaged the steering column bearings/races.
For the OP, rims "should" outlast the bike. Only an accident, collision with road debris, a pothole, driving on flat tires, pretending its a trials bike, or the like should cause a rim replacement. They simply don't wear, at all, in normal operation.
