I don't like the Pentium 4. And after trying to reverse engineer some code for the CDP 1802 I'm not too sure about that one. But what I HATE is crippled CPUs. For instance, the Celeron 766, perfectly fine CPU cursed with a ridiculous locked multiplier for 66MHz FSB long past the time when 133MHz-capable boards and memory were available. Intentionally making things slow is not cool. (Video cards with decent name brand GPUs and horrendously slow RAM also annoy me)
