Given how prolific 3rd party accessory makers are, it surprised me that no one was making an iPad dock with a DVD player in it. Then I realized that allthough the dock connector does video out, it doesn't do video in. You can't use the iPad screen as a video monitor for an external source. A shame, really.

Then I read opened up iTunes, found a movie I'd ripped from a DVD on my PC I wanted to watch. Went and found my iPad, and simply played that movie on the iPad using Home Sharing. Of course the 4:3 screen sucked for the 16:9 movie, which brings me to this conclusion:

The iPad is horrible as a screen for Movies. Skip the idea altogether.
 
My experience displaying netflix, youtube, amazon videos - everything looks astonishingly good, unsurprisingly. iPad has the resolution and picture quality to be perfectly adequate for mobile videos. Why should everyone give up on the idea just because it's the preference for some people to watch on a 16:9 screen? Many portable DVD players don't have 16:9 aspect ratio, and they typically have a smaller screen.

Where's the practicality in lugging around every device you own just so you can watch dvds? In carrying around an iPad and a portable DVD player, or an ipad as well as a TV and DVD player, or a laptop or netbook that has a portable DVD player? It really would be more convenient to just have to account for the iPad and the iPad case.

If you're on a trip you can easily take just a few dvd's, or rent dvd's while on the go. So it actually would be useful to have a case that integrated an iOS compatible DVD player.

Until cellphone data usage becomes a lot more affordable, or wireless satellite service becomes universally available without external equipment, there will be a use for having the ability to play DVD's while on trips, or away from home, or simply away from your home entertainment setup.
