The small travel case is cute and functional, although this projector is small enough to occupy only a small part of a briefcase (as long as the case can handle the almost 3" of the projector's height), which would mean one less thing to carry. Cabling is worthy of comment. The Dell comes with a bunch of cables, including the main data cable with computer and USB on the computer's end and the M1 digital connector on the projectors end, plus s-video, composite and audio cables. The one place you might have to really shop, though, is if you want to feed the 3400MP a component video signal (much higher quality than s-video or composite) through the M1 connector. For this, you will either have to find an M1 to component video, or find a component video to female HD15 (computer input), and use that with the provided cable. I doubt if either is going to be hanging on the wall at Radioshack. That said, those cables do exist (I'm pretty sure InFocus sells a solution in their online store, as they pioneered the use of the M1 connector.
But, back to more important things. Build quality seemed pretty good, but the 3400MP suffers from one problem that many small projectors have: Adjusting the zoom lens after setting the focus, consistantly knocks the projector out of focus, so you have to refocus. Of course, if that is the biggest problem with a projector, then life is real good.
