Strijkbout: VR doesn't stand a chance at success as long as you have to wear a refrigorator glued to your skull.

Spectre: There's some seriously lame excuses going on.

People can ride a motorbike with a bulky helmet. Some VR goggles aren't that bad.

Motion sickness? Just as well people can get over it like driving a car or playing FPS games.

VR's a gimmick like the Wii??
Maybe if your the type of person who's too afraid to do anything more than sit on a couch with an xbox360 pad for fear of shaking your bingo wings. The problem with the Wii was that it wasn't pushed as much as it could have been but it was far from a gimmick and so is VR. Ironically the Wii board would be useful for walking around in VR.

Someone mention a keyboard being the best control. Don't get me started, it's keys aren't even arranged in a layout that's best for gaming.

Price? That's like the argument over the PS3 all over again.
How much does a large LCD screen cost? How much does an expensive GFX card cost? How much does proper joysticks and steering wheels cost?
How much did PCs cost before they became mass market?

A unified architecture might be ok but it can be just as bad for pandering to the lowest common denominator or grant a monopoly like windows.

The only good reason against it is the spyware issue.

HereForTheBeer: Outside of gaming and maybe some niche stuff like medical purposes, are there any other useful, er, uses for VR at this time? I could see how it might a cool sales tool for real estate, automotive, and industries where a walk-around or tire-kicking are the norm but have any of those been developed yet? Beyond stuff like that, what useful things will VR offer to the rest of the world, that can't already be accomplished with a regular screen?

Even if it weren't for my eye problems that place personal limitations on the tech, I struggle to see how VR would improve on the things I already do with a PC, except to make a really huge virtual desktop simply by panning farther in any direction. But even that is reasonably solved with a second or third monitor.

Is it cool? You bet it can be, if done well. Cool enough for $600 and - for now - only a small number of ways to use it? Not for the average person. We don't blink at $700 smartphones because they do a large number of things for us. But a bulky $600 headset is quite limited - and limiting.
