I have them and using on my commuter. They are the reason why I'm going for tubular soon... Changing the tyre is real PITA. imagine that once I had a puncture in front wheel, I struggled 15 min to remove the tyre just to see that the tube was ripped almost in half and I didn't have a spare, just patches, so I put the tyre on went to nearest Halfords, bought spare tubes, struggling again 15 min to fit new tube, go and after 5 min rear wheel got puncture... everything in rain... I came to work 2 hours late. I was using Park levers. Later I bought new tyres (folding) and I couldn't even fit them on.
But maybe it's just only me. Apart from this I don't see any problem, true, straight, everything ok.
Yes the rims run true with no major corrosion or rust, i'm just a bit concerned that running such narrow rims with 28/32 tyres will cause too many punctures.
