HRTF 2-speaker surround sound is the only surround most people will ever experience while gaming on a computer, unless they're plugged into their television/home theater. There's no way I'll ever have rear speakers behind my computer, because they'd be out in the middle of the floor.
Yes, if you choose stands. There are other options.

Furthermore, it's not "simulated" anymore than actual 5.1 surround. The human ear hears it the exact same way....HRTF set up correctly is indistinguishable from having rear speakers. Lastly, headphones are the only truly immersive sound experience you'll ever have, as they shut out your surrounding environs and prevent accoustic anomolies that plague all home theater setups, like sound bouncing off the walls and similar.
I never said it wasn't simulated. All sound reproduction involves compression and decoding techniques, from the old analog phonographs, up to all the different digital formats, processing and voice-coil driven driver technology that is the standard today. I said it was simulated surround, which it is. Unfortunately, you can't mimic having rear sound sources accuractely, anymore than sound reproduction can reproduce actual sound. Headphones still includes acoustic anamolies, nearly all top models are analog so they rely on the sound board for processing which doesn't have infinite bandwidth, nor is the source itself uncompressed.

A3D's "simulation" was perfect. With a pair of headphones on, you could position something around you in a full 360 degree area of effect. (Just like regular 5.1, it still couldn't do sounds above or below you very well.) When using speakers, it was pretty good, but when using headphones actually had better positioning than actual 5.1.
As to why Creative Labs doesn't use it very well, well, they also sell speakers. :p
There's no such thing as a "perfect simulation", so I'm not sure what you mean by that statement. And as you already stated, sound is only processed in a full azimuthal range, without regard to the zenith positioning.
CL's speaker line didn't even become developed or marketed very seriously until they got the THX stamp which is fairly recent in scheme of the last two decades. Their speaker line wasn't even really fleshed out until after Klipsch came to the PC market.
