Displaylink USB video technology introduced the possibility of secondary USB monitors to the technology community. ASUS has now successfully extended this technology to create a unique product, the ASUS UFOTO, which combines the functionality of a photo frame and a secondary monitor. It is a 7" monitor that allows a high resolution display of up to 800x400 pixels (720x480 viewing area).
Century Japan has released a handy 4.3" USB LCD monitor. The unit is designed as a secondary display. Imagine you've been hard at work all day, but you're expecting a specific email or IM. You're tired, and want to go sit in the recliner you have in the room. Rather than having to pop up to your desk every time you hear your email/IM notification sound, just look over at the small LCD display sitting beside you.
