The 2007 International CES was a great showcase of digital photo frames and USB memory keys. There was no easy way to walk a few steps without seeing one or the other - or both.
Perhaps the most interesting digital photo frame is the i-mate Momento. Currently there are no mention of this device in many websites, and Google only returns three results, including an official website for the i-mate Momento, called Momento Live.
I found the i-mate Momento 70 while walking around the Microsoft booth. The frame is enhanced for Windows Vista including support for Windows SideShow, the technology that allows external devices to display information from your system.
With a 7" TFT display (800x400 pixels), wireless LAN (802.11 b/g), SD/MMC/xD/SmartMedia/Memory Stick and USB support it seems this device can do anything and everything. It supports WMA, MP3, Audio Out and includes a built in clock & calendar display mode.
