Re: The difference
ARM is the British tech success version of Apple
Hardly when you consider both the collaboration based business practices and the money earned.
But would ARM even exist without Apple? ISTR that ARM came from a collaboration between Acorn, Apple and VLSI with Apple putting a lot of the money in and Acorn essentially providing the IP. Back in those days (post the BBC deal) Acorn were hardly cash-rich as there weren't enough people like me stumping up for the Archimedes and the RiscPC. Without Apple's injection of the folding stuff we might today be remembering the ARM chip in the same nostalgic "what-might-have-been" way that we remember the Transputer, and our smartphones would either still be brick-sized to accommodate the battery needed for an x86 chip that had no competition, or be Z80-based.
My RPC is still in daily use (it's 21 this year), mostly as a mail server and emailing machine (there is quite a lot to be said for a mail client that doesn't "do" rich text and HTML) but also because I still haven't found a decent replacement for Impression Publisher on Linux.
