Think too yes.

(Fedora)

Fedora usually is pretty nice. I haven't had time/interest to spin up another distro to test if it is Fedora or HW. But the fact that the problem (crashing kernel) persists over multiple versions makes me suspect is HW.

Yes, but it doesn't leave you an installation choice as e.g. Fedora does. I don't massively run VMs on FreeBSD atm, so no need to get that last bit.

The main reasons are: Memory limit lifted, and enough addressspace. (x86 was running out of that too. Where do you memory map a DVD image?). Don't forget that the reason you can only use 3.25GB out of 4 without PAE is because it ran out of addressspace.

And of course the gradual transition, contrary to the previous attempts of Alpha and Itanium. (and maybe PPC)

As you say MSVC and Intel. And yes it may be easier to do so, but I don't think that is it. It probably is more a maintainability issue.

Still have. A Mac 840AV. I'm not the original owner though. 68kwise I had some base models Amiga after I left C=64, but nothing beefy. And then I went to 386sx-20. They are somewhat between a 486 and a pentium. Also iirc they are DX 1 1/2. IOW parts of the CPU run on double core speed (DX2), and parts not (DX).

And we all know there are lies, damn lies and commercials.

If you actually charge for the software optimization is way more expensive. Specially for the more specialized software.

Pascal's, Modula2, C, Java bit of C++ and C# and asm for an arch or 5. (6510,68k,ppc,arm,x86,x86_64. Dabbled with sparc. And several "Microchip" embedded cpu's).

Nearly anything is better than x86, if only for its register starvation, but that was never the question. x86 was clumsy due to the moment in time it was frozen due to the dreaded PC compability. (on Amiga you HAD heaps of programs you could only run with certain upgrades, CPU and videocard )

The i386 arch was already a lot better, and the 64-bit one is again better. And price/performance was always stronger there.
