Human beings had been measuring time even before 1500BC when the ancient Egyptians and Mesopotamians had invented portable sundials. But that was the first time that having time with you was so easy and accessible when Peter Henlein invented the pocket watch.

Those first watches immediately become more than timepieces. In those early days, handmade jewel-encrusted watches were symbols for nobles and kings.

But this suddenly changed in the early 1800’s when Eli Terry Sr, a US industrialist, put the watch into mass production and made the watch what Henry Ford did for the car manufacture company making it affordable for the simple Joe.

The watch technology continued to improve with quartz technology and the introduction of the battery power and even the Atomic Clock’s invention in 1967 had an impact. This clock that uses the oscillations of Cesium-133 atoms to make its time perfect was then adapted and developed until it can be made into a watch.

In 1970, all designs and improvements were done into the watch. LED, Digital, LCD and even calculator watches became available as Japanese companies compete over the market share.

The watch then became cheaper, functional and affordable and in 1998, 500 million watches were sold globally every year.

These days, watch technology has diverted to being green with solar-powered watches, touch screen technology and a variety of other technical features being added.

It is unavoidable then that the watch be added with MP3 and MP4. The arrival of flash-disk technology and the watch interface was really a perfect match and many electronic suppliers have done with making plastic watches and are now moving to high quality materials like steel and gold.

Christmas holidays are just a few weeks away. People will be traveling or just staying at home for this special season. Most would be just relaxing at home and watching movies in their entertainment sets. But for people-on-the-go, you don’t have to leave your home entertainment at home.

For those traveling, usually you get bored during the long hours of driving and staying at the back seat of the car. People who are used to having their usual entertainments at home are forced to leave these luxuries once they travel. This would also be a danger for those having their business trips and they won’t have any idea whether they would be provided with the appropriate audio-visual facilities for their presentations.

Now some manufacturers came up with something to solve this. Portable DVD unit is small but have a lot of features that includes a portable DVD television and a NES emulator for the kids.

These DVD units can connect to anything because it has an AV in and out points, a disk port, USP port, card readers for SD, MS and MMC. It can also accommodate from DVD to CD or RW disks and JPEG, WMA, MPEG, MP3 formats easily.

Those people who travel but wants to bring their comforts with them or for people who needs to have a presentation in places with little audio-visual facilities would want to have this. But it would cost a few hundred bucks.

The portable DVD players which are dual have more than the portable DVD player in the stores. These dual portable DVD players have their own 14inch LCD TV screen that moves on all sides, connected to its unit.

This DVD is to be bought for the next vacation.
