I certainly agree with your assessment 1Freon1 about the users. Athlon's are definitely favored by gamers and the low end Celeron's by businesses who don't want to spend a lot on the hardware. A Celeron is an Intel processor that didn't quite make the testing "benchmarks" set for a true Pentium (sort of an "Intel second"). Most of the overheating issues can be managed by adequate and "quality" fans, properly vented cases and sufficient power supplies. I suspect those who have problems with Athlons, including the place I buy my computers, simply don't know how to set them up properly and don't want to spend staff time on it. Every computer has certain nuances. Another firm in town promotes the Athlon over the PIV for the very same reason......for them the PIV is more problematic. I suspect it's because they are most familiar with the Athlon and cater to gamers....and there's a better "profit margin" on the Athlons. I guess there are "zealots" on all sides of this issue. I've always had Intel based computers, but would certainly not buy a Dell (or an HP, Compaq, etc.) for my personal computer! Now....that's my bias. I have mine built to my specifications. That way I get the OS and the hardware that I want.....not something the manufacturer thinks I should want.
