• Almost unlimited storage--some devices claim to store up to 3000 titles
• Download books wherever there's an internet connection available (may require network registration)
• Text-to-speech software lets the device read to you--set male or female voice and 'read speed'
• Ability to change font size eliminates the need to search out traditional large print books
• Text search, annotation, highlighting, bookmarking within each book
• E-Ink technology offer readers a near-traditional print reading experience
• Digital books are generally less expensive than their print partners*

•• Devices run on little power, allowing near-continuous use for weeks at a time before recharging is required

•• For the author, it means a book need never go 'out of print'

•• Let's face it, digital books are Green/Eco Friendly--No ink or trees go into the production of books

•• And probably a very important disadvantage -- the USA's Federal Aviation Administration requires the prohibition of e-book reader use on commercial airliners during takeoff and landing. But we should already be used to this with CD players and computers, as their use during takeoff and landings has long been banned

• Let's start with the '*' above at [digital books are less expensive than their print partners*]: Digital books released at the same time as hardcover titles are generally priced similarly until the book goes into paperback format 6-12 months later, especially in the case with branded authors like Dean Koontz and Nora Roberts
• Technology advances . . . top of the line today can be replaced by the 'new and improved' model tomorrow
• Proprietary formats: While all devices support epub and pdf formats, some also operate on their own format, such as mobi with Kindle
• Traditional devices are only designed for reading mass market type books
• Devices are susceptible to damage, aren't waterproof, and can't take extremes in temperature. If your books aren't backed up, those titles could become lost if your device fails
• There's no used digital book market, especially for books with DRM, however this is beneficial for the author who makes royalties off each new sale
•There's nothing like a trip to the bookstore, wandering the aisles for hours, flipping through volumes before buying what you want

••As with mobile/cellular phones and other trendy electronic devices, theft of digital readers is on the rise

•• What to do with old or obsolete devices when you trade up? *note: recycling centers are beginning to take these devices, as they have long accepted computer componants and other electronic goods
