I know that there are a vast majority of people who prefer to only use a PC w/ keyboard/mouse for browsing. However (just like with the network picture folder access), these are also likely to be the kind of consumer that will not be setting up a networked digital photo frame, specifically with online photo sharing sites. The other device to consider in regards to the lack of a physical keyboard is the iPhone, which has demonstrated (to me) that the web is mostly experienced by the pointer, and the keyboard is used mainly to launch the experience. My biggest problem with the iPhone is that the size is too small, and the keyboard is not available in Landscape mode throughout the OS.
