XrossMediaBar: Limited to Sony Products?

[Kevin Holly]

Hey, I didn't see any topic about this, so I figured I'd create my own.

Is the XMB interface limited to Sony products? Or do some other companies use it?

Also, do ALL Sony BD players use it, or just some?

If other comapnies do not use the XMB, do any have any that are comparably awesome, and, if so, are there videos on YouTube or whatever of people using them?

Thanks!
