The remote thingy at Dell will need some permission from the customer before they can remote into the user's PC... and standing infront of a webcam, that you know is activated is just plain Stupid!
that woman is just after some cool cash from Dell... but its ok, Dell itself is a scam anyway...
imagine their software support, called Dell On Call, which now became Support Something? they charge people a whopping $129 or $239 just for looking at or running an anti-spyware scan which are for free.
