I'm really disappointed in Intel. The TIMNA was a brilliant idea in line with the Cyrix Media-GX chip. $100 PC's were within grasp. Now that they decided against it they'll move to more expensive endeavors.
Bottom line is that a 486 can do the internet. The 486 could clock at 800mHz on the .18 process, and possibly hit 1gHz on the .13 process. The chipset on the 486's was simple enough cpu, USB and PCI controllers, and memory chipset could have been pushed into a die about the size of a dime.
Intel's marketing department has pushed for all this fpu and SiMD crap to spur their sales. They've yet to enjoy their technology long enough to develop it all the way through. Rather, they push new unproven techniques at every turn. SSE and MMX doesn't enhance the internet experience. Nobody needs the fpu unit to browse HTML. Like I said before, the 486 was plenty for the internet...
