Customer comment from the Samsung website:
Well Just got my 10.1 here in the Netherlands, Big Disappointment as there is NO microSD card slot, BUT it looks like there will be an adapter (German Vodafone Site) that will allow adding the USB/microSD card thru the 30pin connector... not an Ideal solution but better than nothing I guess... As for the Rest the 10.1 works like a champ, and the UI is very slick / and response time are very good. Out of the Box I would rate it 7 Out of 10 Lack of the USB / microSD card slot is a real disappointment.
