This is what you ask a computer salesman
about to see if he's on the level. "Sure, this system has USB
... but does it have LRF support?"
If he says yes without batting an eye, look out... this guy's willing to say yes to any question if it'll get you to buy
If he says he doesn't know what you're talking about, he's probably okay.
After you buy your computer, you might want to determine if it does in fact have LRF support. This is easy to do: turn it upside down and see if it's support
