Beware: You can't charge Samsung Galaxy Tab Via USB connected to Desktop/Laptop

I stumbled upon this update on Engadget -

Update: Well, this is a bit crazy. It was brought to our attention that the Tab cannot be charged via a laptop or desktop. And that is in fact the case -- when plugged into a USB socket the Tab will maintain its charge, but won't be recharged.

Just posting it here to make sure that the buyers are aware of it.
