but it's time to take the next step... we've been on this step for 20 
years now..

Intel, AMD and others are making sure that x86 will live on for 
another 20 years! Billions of dollars can't be wrong. 

If we look at real profits being made by real businessman, this is how 
the top 5 CPU classes line up. 

x86 -- Intel/AMD/Via/SiS/NatSemi(Geode)
PPC -- IBM;Motorola;some SoC
Sparc -- Sun;Samsung?;a handful SoC
ARM -- Intel(StrongArm/XScale); TOO MANY SoC
MIPS -- AMD(Alchemy);NEC;PMC;Broadcom; many SoC

The x86 has been way ahead of the pack and may continue to be even 
after we all switch to Linux/BSD.

Most commodity WiFi access points  have switched to the $10 Ubicom 
IP2022 which started life as a PIC compatible 8-bit microcontroller. 

It is so fast and deterministic that Ethernet MAC AND PHY are both 
done in pure software!

However, it is really not fair to compare such an I/O procesing feat 
with the abilities of a general purpose 32/64 bit CPU.
