I got a bad taste in my mouth for AMD clear back when I bought my one and
only 386SX-20 because it wasn't completely compatible. Some applications
wouldn't run on it. I haven't owned an AMD since.
That would be a VERY long time ago. Sort of like saying, 'I got a bad
taste in my mouth for Microsoft when I bought WinME and found out it
was bad stuff', I've not bought a Microsoft OS since.
Like hard drive manufacturers, the two CPU guys shift places from time
to time. I preferred AMD K6-2-400's to similarly priced Pentium II's.
I liked the faster P3's as they ran relatively cool. I shifted to AMD
XP's -- though some ran hot, because the Pentium 4's were pricey, and
then as they P4's moved up the performance ladder, THEY ran hot (and
the Retail fans were LOUD).
When the AMD 64's came out I was impressed with their price,
performance and that they ran nice and cool (and quiet even with stock
fans). The 939 Dual cores were sweet, and I like the X2 Dual cores.
But the newer Intel dual cores offer marginally better
price/performance, though they still run hotter than the AMD's.
Hard drive manufacturers do the same thing, for the longest time, I
really preferred both WD and IBM, I ran away from IBM when they started
failing when subject to high duty cycles. I avoided Seagate IDE drives
(but found their higher end SCSI drives to be excellent). Then WD
seemed to get in to a bit of a reliability funk, and Seagate started
producing nice drives which ran quiet and are quite reliable.
All this is to say that while I 'punish' manufacturers for bad cycles,
I don't elephantize my memory regarding them -- after I've heard and
seen a change, I respond to it. Your mileage and approach of course
may vary.
