While ARM is nice an ARM monopoly is no better eventually than an an x86-64 one.
It's a pity that there seems to be so little diversity?

On microcontrollers there is less diversity too. Interesting that there are 50 cent 32bit ARMs competing now with 8 bit chips such as 8051, Atmel, Microchip PIC and embedded Z80 and 6502 in ASICs. The 32 bit ARM cores now in ASICs and FPGAs replacing old 8 bit cores.
