Fugi x10 noot registering on Mac OSX
The direct connection is no slower than using a card reader and saves wear on the SD cards contacts - and the camera's. There is also a problem with OSX Lion and fast SD cards which causes some cameras, including the X10, to waste time rooting around in the card's directory structure which can make it look as if the camera has not woken up when switched on.
Formatting the card is the answer to that problem. But otherwise I use the cable all the time and have no problems.
