Bought this for my 77 year old Mum so ease of use and good display were my priorities. My PC recognised it immediately, as if an external drive, and using XP creating a folder then dragging and dropping photos was a cinch. Wondered if the frame would need photos in the root directory but it was fine. The display is gorgeous - most of my photos taken with my Nokia N95 and look crisp and colourful. Some on an old digital camera, also good. Even ones from my Nokia 6600 are viewable if a bit grainy from the increase in size.
The manual appears to be written in English rather than translated, and is well-indexed. Mum was quite happy to read it. To be honest, I could have got the frame set up and photos on it without even reading the manual, it was that straightforward.
I stored nearly 200 images on the internal memory.
The remote control is easy to use and some of the icons are self-explanatory but the manual covers these right at the beginning anyway. It takes a standard calculator battery.
Only gripes - the auto-orientation doesn't work on my photos, and although you can manually set it for a still image, this doesn't seem to work in random mode nor retain the change. The answer to this is edit it first on your PC! Secondly, no mini-USB cable is supplied, so you might want to buy one if you can't pinch one from something else (in my case, my 3G modem). Finally, I was surprised to read in the manual's advice, that memory cards should be formatted on your digital camera, not in your PC, otherwise they might not work. I haven't tried it with a memory card so I can't comment, but not sure where this leaves micro-SD cards or similar from one's phone. Not everyone has a digital camera, especially with phone cameras now being so good.
Small gripes and certainly nothing that would prevent me giving this 5 stars. I want one myself!
