The Most Portable DVD Player – that’s what this particular portable dvd player bills itself as. Since it’s actually only one inch thick, I don’t plan to second-guess the claim.From Shop.com:

This portable, handheld device allows you to watch DVDs and listen to CDs and easily fits into a carry-on bag because it is only 1″ thick. The unit has a 3 1/2″ TFT LCD screen that can redraw images faster than typical LCD monitors, resulting in a sharp, clear, and detailed resolution. Integrated anti-skip circuitry maintains uninterrupted viewing during turbulent flights or bumpy car rides, and it provides multiple viewing angles because it can be adjusted using its integrated stand. Compatible with all CDs and DVDs, this unit has two stereo speaker, and includes a headphone jack for private listening. With a remote control, a lithium-ion rechargeable battery pack that lasts up to three hours on a full charge, AC adapter, DC car adapter, and a carrying case. Connects to a television via included AV cable. 6 1/4″ Diam. x 1″ D. (4 lbs.)

Sounds perfect for students, and I can see just about anyone taking it along for a long day at the office – what better way to make time fly than to have a little fun with it?!?! Beats working.
