Have you ever been on a long boring bus or train raid just looking out through the window with out anything to do? Wouldn't it be nice to be able to watch your favourite's movies on your way to your destination instead? A portable DVD player allows you do just that. A portable DVD player is a small DVD player with a small screen attached to it allowing you to watch movies where ever you. Now you might be thinking so what, Portable DVD players are nothing new. That’s true but it's only in recent time that they have become inexpensive. Today almost everyone can afford a portable DVD player.
A portable DVD player plays regular DVD discs or "Digital Video Discs". A DVD disc is 4.72 inches (120 mm) in diameter and can store 4.7 GB of data. They work in the same way as CD discs but utilize a shorter wavelength laser and can therefore store a lot more information on a disc than your standard CD.
Most Portable DVD players can read regular CDs as well but is still not suitable to replace your portable CD player. This is due to the fact that even if DVD players can read CDs they are specialised to handle video media and will as such not handle music as well as a unit specialised for musics. This does not need to be a problem and you might very well feel that the sound quality in a portable DVD player is good enough to use it as a CD player. You will however feel differently if you are a "Sound snob". CD players can't play DVD discs since reading a DVD requires more advanced and sophisticated technique than the technique in a CD player.
One my wonder why portable DVD players hasn't been available at low prices for a long time when the technique used is similar to the technique used in CD players and portable CD players have been around forever. The answer is simple. A portable DVD player requires a large amount of miniaturization of technology to make it possible to fit so much into a small container. A portable DVD player does after all not only contain a DVD player but also a flat screen, all of which should fit into something that you can easily hold in one hand.
I mentioned earlier that portable DVD players today have become cheap enough to allow the average Joe to get one but does one actually need one. The simple answer is no. You could just bring a book or a deck of cards along with you on your trips which both would give you something to do on your trip and are considerable cheaper than a portable DVD player. A portable DVD player could however give you a lot of fun and a cheaper model could very well be worth considering since they can bring you some fun even though you don't actually need one. And sometimes one just feels like spoiling oneself with something one don't actually need. I know I do.
