The eReader market is hot. Barely a day goes by without an announcement of a new device release or acquisition. It is no surprise that eReaders are becoming increasingly popular. After all, people always love the thrill of owning a new gadget. But is there more to this device? Would it appeal to the book readers as well as gadget lovers?

eReaders are light. Often weighing less than your regular paperback, an eReader will provide you hours of entertainment on a long trip. Keep in mind that an eReader would hold hundreds of books, so if you are used to taking 3-4 paperbacks on your long trips this is a wonderful solution for you. You will have great variety and a constant supply of reading material.

The eInk Technology. You have to see it to believe it. It looks just like real paper. Your eyes never get strained and the experience is as close to a normal book as possible. It is much different than reading from a laptop or a palmtop where the flicker and the back-light of the display will make you get tired after 30 minutes.

Variable font size. Leading models will offer you to adjust font size to suit your needs. This is definitely something you cannot do with a regular book, but a much needed feature for those of us who're approaching our better years.

Battery Life. The battery supply on these devices will last for two weeks, which is remarkable. This long battery life is thanks to the eInk technology. A display using eInk only draws current when a page is flipped. So, it doesn't matter how long you have it on, as long as you are on the same page no current is drawn from the battery. And when you do flip a page, it draws a small amount for less than a second.

Multiple formats. Multiple file formats are supported by the top eReaders, so you will never be left without enough books to read. Wherever you choose to acquire your ebooks, the leading eReader devices would probably support that format. PDF files are supported on some, which is great if you are a student or a business professional.
