with laptops far outselling desktops world-wide, I can see why Intel is pushing for this. The bigger market is with laptops where the CPU is rarely replaceable. Simpler for intel and simpler for manufacturers.
for folks who dont know, this corporate mindset is even worse at apple. Their thinnest laptops have the RAM soldered onto the board with no expansion possible. the newest rumor is that the new imac desktops (with super thin bezels) will have no RAM expansion, but that isnt confirmed.
