i have just taken the plunge to upgrade from a pentax mz60 to the k20d. what i would like to be able to do is download the pictures from my sd card to some form of portable storage whilst on the road, so that i dont have to carry a load of sd cards and also can leave the sorting out of the photos until i get home. i would also like to keep my collection in portable form in order to be able to show my pictures to friends and family. am i better with an external hard drive, a web book or a plain old laptop. i would like something with a reasonable size screen, ie 7" x 5" or more. thanks in anticipation john allen
