Not sure what there is to dislike about the AMD Heatsink clip ... no worse than socket 7.
It varies as well, some heatsinks only use one point on each side, while others (larger, heavier) use all 3 points on each side - and the really big monsters are sometimes bolt-through.
This article is an interesting take on Intel vs AMD

Looks like AMD shaves it on cost, but needs a better heatsink to overclock.
But they really rate the Intel 2.4C with motherboard and RAM capable of pushing to 275MHz - the normal "800" is 200 quad-pumped - that's dual DDR INTERLEAVED, not just feeding into the chipset and waiting like in Nforce2!
AMD K7 Motherboards also tend to be cheaper, so the AMD is probably still the CPU of choice for budget systems.
AMD64 has a hard task though - to replace the previous range, will need a cheap version (I guess they could Duron-ize it) but also economical motherboards - even better if they had DX9 onboard graphics.
While to displace Intel, it needs performance/price again - only more of it.
