I've had mine for over a year now and I agree with many of the points in this review. I don't fly with mine nearly as much as the OP.
I wrote a little feedback last year in this thread:

I agree the latches on the Tumi 19 aluminum are outstanding. The wheels are also very nice and so is the overall design of the suitcase. I have two of them, both in black. One is the iata sized carry on and the other is the short trip 26". On one trip one of the wheels got broken off, the tumi store replaced the wheel within a few minutes no questions asked. Second time the corner piece got cracked somehow, tumi store replaced the suitcase under their one-year replacement guarantee again no hassle whatsoever. I would say however the the Tumi feels more finished than the Rimowa. Most of my Rimowa cases don't shut straight anymore (granted they are many years old), even my last purchase from a year ago [Topas Stealth IATA carry on] seems to be already out of alignment.
