Am also interested in Epson PictureMate or similar (e.g. HP Photosmart). Surprised to see no response to emmaneldo's post yet, so would like to add a couple of specific queries:
1. Are they truly portable -- e.g. can they be packed in your luggage without ink spilling everywhere?
2. What is "new" about their printing technology? Epson and HP both say their photos will last longer than normal photos.
