Just to gripe -
Our hobbist equipment, on old xti, a Sony A100, take it out in the rain, bump it on rocks when hiking, leave it in the car in 90 degree weather, in -10 degree weather. No problems, never an error code or a failure after 5 years.
Our 5D, we treat like glass, only use it for the professional jobs, always in the case when it's not being used, never leave it in the car, don't take it out in adverse conditions. A year and a half and it needs repaired.
Got to love the extra quality that goes into the professional grade stuff.
