Decisions, decisions: which gadget should I buy?

You probably won't be forced to choose between a tablet or ereader or make other similar difficult decisions very much longer. One reason, of course, is that their capabilities are being merged in ways that may make a single device suitable for many uses - but that is not the main reason you'll avoid these agonizing choices. With all the uses for this versatile crop of new devices, it's very likely you'll have more than one. We certainly have numerous magazines and books on hand not to mention newspapers. If tablets, ereaders and smartphones become universal tools, a family will most likely have several.

After all, it's not uncommon to have multiple PCs in the house; it often makes sense to keep an older machine when upgrading since they have little resale value and work quite well at common tasks. Of course students regularly use computers for homework and the competition for "the computer" can get fierce in the evening.

It's important to note that we are in the early stages of the Mobile Revolution and dozens of different shapes and sizes of devices will come out soon. Distinguishing between tablets and smartphones will become increasingly difficult and naming conventions will evolve rapidly.

In any case, it is quite likely that a variety of tablets and other mobile devices will be used to replace collections of books, magazines and other publications. No matter how much we enjoy the feel of a "real book", we will rely increasingly on electronic means for much of our information and that means more electronic devices will be needed for access.

Ebook formats and other issues

While the Amazon Kindle may be the best known ebook reader (ereader) around, it is certainly not the only one available today. This brings up the question of compatibility and formats. An entry in Wikipedia lists 21 different ereaders using 13 different formats. That's not a misprint - 13 different formats. Fortunately some ereaders can read ebooks in multiple formats and seven formats are the most commonly encountered (Plain Text, PDF, ePub, HTML, MobiPocket, FictionBook and DjVu.)

Probably the most vexing but least discussed question concerning ebooks relates to your ownership rights. When you buy a real book, there is no questions what you can do with it - keep it, sell it, give it away or throw it away. What happens after you pay for an ebook? Can you transfer it to another similar device, another different type of device, a device owned by a friend, etc? Can you in fact create an ebook "library" like you would with real books? For years people have erroneously thought when they "bought" software they actually owned it - wrong! Virtually every software product includes a license agreement which strictly limits what you can do with it. You do not own software; you are a licensed user.

I firmly believe ebooks are the way of the future. It is just not clear how that future will develop and there are certain to be some unexpected bumps in the road along the way. Not surprisingly many of the issues (formats, licenses, etc.) are what we've dealt with for years with software.

E-reader fire sale?

If you're thinking about taking the plunge and purchasing one of the many e-readers (sometimes called e-book readers), you should know that competition is heating up. New models - some with color screens and other extra features - will be introduced over the next few months. For a discussion of what's happening read this excellent Computerworld article.
