I wish Microsoft wasn't the only one.
Part of the reason geeks love *ix is because right now the alternative is Windows, and *ix matured rather better than the odd combination of technologies (an API and application model with its roots in Windows 1.0 coupled with a nice-ish kernel with inspiration from the unholy combination of VMS and the 1980s microkernel movement) that's called Windows today.
Throughout my life I've used a variety of different platforms, though the ability to choose something different dried up in the mid-nineties as one by one the alternatives either went bankrupt or became obsolete. Some - at the time I was using them, not now - felt more comfortable, flexible, and ultimately more usable, than *ix. AmigaOS 2.04+ (especially augmented with the GCC tools) would be an example (again, NOT NOW, THEN.) Others, like VMS, were ugly, and horrendous to use or program, but they were still valuable in terms of providing wonderful ideas that, alas, we've ignored since - VMS itself had generic job queues, indexed files right in the file system, a shell that didn't blindly execute files with the same name a command you'd typed, security passed upon roles and permissions, networking built into the file system (think if you could type "cat header.html scp://otherhost/home/squiggleslash/main.html footer.html > blah.html" - that's roughly what I'm talking about), all unfortunately crippled by some clumsy design decisions and a reliance on proprietary hardware.
*ix is great, but for those who've experienced more than Unix and Windows, it's... well, it's kind of like we settled. You know that couple who knew each other at high school, and then after a 20 year absence got married at 40? And they seem OK, but you realize both are bored, and both married because they felt like they were running out of options?
That's us and *ix.
