So since 1984 we've had 68k, PPC, and Intel... now we get ARM-based chips from Apple.
Cool - a new architecture every 10 years? Whereas Wintel has been the same all that time. Be interesting seeing how this (and the depreciation of OpenGL - which presumably won't get ported to ARM) will impact my usage as I use a lot of self-compiled emulators and stuff.
For example right now I use Mednafen (as a Saturn Emulator) and Reicast (as a Dreamcast emulator). Unless I can compile these for ARM with Metal, I might have to stick with Intel Macs or switch to Windows. I know this is just gaming but I don't use my Mac for a lot more than word processing (don't use Pages/Numbers as my colleagues all use Office), web browsing and casual gaming. Hopefully some devs have already thought this out and there will be ad-hoc fixes...etc (at least for converting stuff to Metal). Emulation on ARM? Can only hope for decent ports as that's way above my (basic) programming skill level.
