David Pogue reviews several of the latest digital picture frames at the New York Times: I have frankly avoided reporting much on digital picture frames, even those with wireless, because so many of them seemed far too expensive for their simple function of automating a rotating display of photos. Product announcements seem to come weekly, which means that a lot of people are buying these for their parents and grandparents, loading them with photos, and then the same pictures display for the next year until the relative takes it down and claims it "broke."
Pogue makes it clear that I'm not far off in avoiding writing about these frames. He likes the Kodak EasyShare EX1011 at 10 inches (diagonal), which supports Wi-Fi, but not Mac OS X, and which can link up to Kodak Gallery to pull in new photos over the Internet from galleries you update from wherever. That really does make it appropriate for computer illiterate relatives. Or those who just don't want to monkey around. The 800 by 480 pixel resolution is also quite reasonable for that size of display. Pogue notes that the dimensions, however, put it into a widescreen orientation inappropriate for most digital photographs.
At $250, though, that's a hefty gift and I find hard to swallow despite the screen size and inclusion of Wi-Fi.
Pogue also likes the much cheaper PanDigital Wi-Fi Picture Frame ($150, 8 inches) has Bluetooth and Wi-Fi but can't use Wi-Fi to grab locally hosted photos, just from Picasa.
He has kind words for the SmartParts SP8PRT ($280, 8 inches) frame shipping in March that has no Wi-Fi but can print photos through a built-in, hidden dye-sublimation printer. I find the idea a little funky: why print from a picture frame that you have to load with photos from a computer? It seems like you'd want Wi-Fi most of all in this kind of device to send pictures to others, and they could make prints of photos they like.
Three others, he generally excoriates. The Parrot DF7200: "the resolution is so coarse...it's not a big improvement over your cellphone screen." The eStarling second attempt: "...even though this frame is much better than its disastrous first model last year, it’s still flakier than a croissant." Momento 100: "Photos from the Web arrive on the frame at half size, bizarrely floating in the center surrounded by fat black margins."
There's a lengthy comparison chart also online.
