(1) Portablilität: It is in my view one of the few devices that comes with a rechargeable battery and ideal for the presentation of images untwegs or friends is (a request of the recipient). The battery lasts about 2-3 hours in presentation mode (slideshow) or even with the manual selection of images.
(2) Internal Memory: 4GB internal memory are a lot of photo collection. Both the original sizes of the images were (Canon 450D, JPEG format) tried and reduced size (1600x1200, 1024x ... and 800x ...). The number to be stored should be sufficient for household use. Unsuitable is in my view the use as a "backup storage", since the speed of the disk type of construction can not compete with a traditional hard drive (it should also not ...).
(3) Ease of use: The menu is in my view simply and also for "older term" easy to handle. Criticism is the already mentioned lack of a way to categorize the images during aufspielens. Also Ordnersrukturen be ignored, however, all images contained in the folder appears. Since the device was intended as a gift, about 300 images have been partly filled with once. These must be assigned to categories unfortunately cumbersome on the device. (For users with computer experience and example Picasa rather annoying because consuming). This should be rectified by the manufacturer!
Otherwise, the equipment meets the expected properties and is just for "home away from home" presentations of photos super useful, in my view.
PS: kudos to Amazon for the smooth handling of transport damage and that too in real time over the Christmas period. Great !!!!
