If it weren't for the fact Win98 becomes highly unstable when attempting to use it on my AthlonXP board, I'd still be using it today. As it stands, I'm sticking with Win2k untill either I run into the same hardware incompatabilities, or AROS becomes functional enough to replace it as my main OS.
MacOS X was actually my idea... Mine and probably thousands of others who emailed Apple to let them know their original OS sucked, and didn't even come close to touching the capabilities of their excellent hardware. My email to them suggested a posix compliant OS such as BSD.
Behold, the darwin BSD kernel, the core of OSX. Sitting under a nicely prettied up X interface.
Since the move to RISC86 processors, I don't see it being too far into the future that Apple abandons their computer hardware entirely, and sells OSX for use on PCs. I'm betting they're making way more in iPod sales than on their computers... And it would create a direct, wide-spread competitor for Windoze... With plenty of industry support. Far more than even Linux has.
But back to the topic at hand, Windows Vista is a much needed move to directly support the new 64-bit RISC86 processors, as well as take better advantage of the wave of 3D accellerators.
That said, given the massive overhead of Win2k and XP, I shudder to think what Vista will require just to run itself, nevermind applications. Running Win2k myself, the system cache alone sucks up 287MB of my 512MB memory.
287MB of RAM JUST FOR MY OS?! That's absolutely absurd! XP is even worse, tho the hype says it's supposed to be an improvement. At least I can RUN Win2k with 128MB of RAM or less... Try it with XP sometime! Linux is getting just as bad.
So, I'll wait patiently for AROS to gain more functionality. I've seen how small a footprint it has, as well as what it's capable of. Proof we don't need hardware hogging operating systems.
