I purchased this exact model frame about 2 Xmases ago as a present for my mother. Specifically the wood finish one. Back then I got it refurbished as a steal of a deal for, I believe, about $75 on a Xmas sale from Phillips's online outlet store. It was actually A LOT of work, the sale was so popular that literally for 3 or so days their servers were getting hammered, so it took about 5 minutes each click for the server to respond, if it even did, most of the time you'd get a server 404 or 500 error, and THEN even when you did get a page 90% of the time their SQL server was putting out errors, so it literally took me 2 straight days of continuously trying to get it... That's how much of a good price that was.
This frame is NICE, I really recommend it. The frame is plastic like most of them, but unlike most of them, Phillips does a nice job with the frame (I'm talking the border) they may be plastic underneath, but they don't have that plastic LOOK, they look nice, especially when on a wall or tabletop. You can stand them horizontally or vertically, or mount them on the wall. There's a mini thumb joystick on the back by which you navigate, and press in to select things. You have a choice of different transition effects (or the choice of no transition), the choice of how long each picture stays up, to display a clock in the corner or not, etc. I found the UI relatively intuitive. And it is pretty easy to set it so it displays the pictures randomly in an endless loop.
I had trouble with the Phillips software, it didn't seem to work well on my Vista 64bit machine back then, but it didn't matter, it's really not necessary. If you connect the frame via USB to your computer its internal memory and any flash cards you put in it will show as drives on your computer like any thumb drive or flash drives do. And you really just need to copy photos over. But keep in mind if you don't use the Phillips software, you'll want to first reduce the pictures to 800x600 because they take up less space and the frame then has to do less work to display them. You don't HAVE to, but if you don't the files are larger (so you can't fit as many), and the frame has to reduce them itself before it can display them. There are many free programs out there that can batch reduce a bunch of pictures for you in one go. Doing that, I was able to fit a few thousand photos onto one 1gb SD card for my mom. It's sorta neat, you can sit watching the frame and almost never see the same picture twice.
I can't say it gets much use but a nice feature of this frame is that it has a built in rechargeable battery, so, useful for gift giving because if you filled it with pics for them they can literally turn it on right out of the gift wrap. Or say if someone picks it up and wants to pass it around, they can just unplug it and do just that.. So yes.. your power might go out.. but your digital frame will still be showing pics!
