· It will not display progressive JPG photos (not mentioned anywhere and took me a while to figure out).
· Deleting a RSS feed will not remove the photos that’s stored on the 64MB internal memory (only 32MB allocated to RSS feeds). You’d need to physically connect the frame to your PC’s USB port to do this.
· It will not store and display older photos from RSS. For instance, Flickr RSS feeds only show the 20 latest photos in your selected stream (filter by tags or sets possible). Your older photos will likewise drop off from the Samsung frame.
· Will only display the 1st photo of a RSS feed post. e.g. If you point the frame to a blog post and there’s more than 1 photo per blog entry, only the 1st photo will be retrieved by the frame.

Other things that could be improved upon (with better firmware?)
· Allow you to access the SD/Memory cards as external drives when plugging the frame into your PC’s USB port.
· Allow for longer slide show interviews. Photos switch too quickly, even at slowest setting.
· Allow the RSS to save to SD/CF and not be restricted to the tiny 32MB on board storage.
· Allow for option of a less obtrusive clock/calendar display
· Allow for an increase in the frequency of updates from RSS and/or allow for manual refresh.
· Better RSS compatibility.

Overall, it’s an average photo frame. It display photos will a slight wash-out color tone, like they were taken under harsh lighting. My older Philips (non-wireless) digital frame had much warmer colors.
The wireless functionality definitely needs work, hopefully to be addressed by future firmware updates. BTW, my firmware ver 1002 didn’t come with a Frame Channel activation code.
