I don't have mine yet, so I haven't actually done the comparison, but this is what I believe from what I have read: A laptop will have a better picture (bigger screen and better quality), while a portable dvd player is smaller and therefore more portable. Depending on your laptop, there may be a difference in battery life. The only other differences are the cost, and the computing capabilities of the laptop, which the dvd player will obviously not have. Other than all of that, I believe they should both play dvd's equally. So basically, if you want more bang for your buck, get a laptop, and you will not only have a portable dvd player, but you will also have a computer. If you want a really cool gadget that is extremely portable, get the portable dvd player. If you are a millionaire, buy both, and be sure to get the top of the line.
