No, I’m not going to tell you that one is vastly better than the other. It’s not that simple.

Early adopter that I am, I purchased my first Kindle not long after the device came on the market. Within weeks, I had found a new love-object. It quickly became apparent that I was able to read books much more easily, quickly — and, yes, pleasurably — on the Kindle than on paper:

  • More easily, because I could carry the Kindle with me anywhere, snatching 10 minutes here and 20 minutes there to move a little further into the meat of whatever book I was reading;
  • More quickly, because the line length, using the large type I selected, was short enough to allow my eyes to skim more rapidly over the text; and
  • More pleasurably, because I wasn’t forced to bend books at the spine, hold them down with my elbow, or prop them up with a pillow because, since they were often thick hardcover editions, they were uncomfortable to rest on my lap in a chair or my stomach in bed.

The advent of the Kindle 2 made this happy camper turn somersaults. I loved the longer battery life and was even more pleased that no longer could a subtle swipe across the device turn the pages far back or far ahead and cause me to lose my place.

That helps explain why I’ve read a total of somewhere between 150 and 200 books on the Kindle — and practically none on paper.

Now, enter the iPad. Tempted though I was when the iPad was first announced, I resisted the impulse to be the first kid on my block to own one . . . until I learned that Amazon.com had created an app that would allow me to download books previously available only for the Kindle. (The library of available books on Amazon.com is vastly bigger than what’s available anywhere else, and especially from Apple.) I immediately bought an iPad and reveled in the oohs and ahhs of my coworkers and friends at the sheer beauty of the device.

Then I tried to install it. Unbeknownst to me, the iPad is not a self-contained computer. It must be installed through a “real” computer — in this case, my new HP laptop running Windows 7. Turns out, though, that Windows 7 isn’t overly fond of the iPad. After an hour or two of futility, I turned to a friend for help who is a certified, grade-A geek. It took him more than three hours to get the machine running. I had further trouble getting it to “sync” with my laptop, but that’s another story.

Apple includes an edition of Winnie the Pooh with full-color illustrations as a starter in the iBooks library, and as you may already have seen, it is wondrous to behold — nothing short of gorgeous. But I was more interested in reading books from Amazon.com, so — with some renewed difficulty — I downloaded the Kindle app and several books from my archive at Amazon. Another delay ensued when I couldn’t figure out where those books had gone on the iPad, but another techie friend solved that problem without difficulty.

Finally! Days later now, I opened my first Kindle book on the iPad — and felt cruelly betrayed.

Here’s what you can’t do with Kindle books on the iPad:

1) You can’t adjust the size of the type. You can only switch from landscape view to portrait view and back again.

2) You can’t look up words in the dictionary, because there is none.

3) You can’t get a sense of how much of a book you’ve read, because not only is there no pagination (there isn’t on the Kindle itself), there is no indication of the percentage of text you’ve completed or any comparable mechanism.

4) You can’t see the cover in its full-color glory. (You can’t do that on the Kindle, either, but you most certainly can with iBooks on the iPad.)

In short, buying an iPad to read books from Amazon.com is a non-starter. Perhaps the Kindle app will be improved, but it will have to go a very great distance to equal the amazing performance of the iPad with books from Apple’s online store. Here are a few of the many capabilities of the iPad in book-reading mode:

1) You can switch from landscape to portrait view, or vice versa, and lock either one in place.

2) You can adjust the font size by tapping an icon located in the upper-right-hand corner of the page.

3) You can adjust the brightness of the backlighting by tapping on another icon, located right next to the font symbol.

4) You can search the book using a keyword or phase by tapping a third icon — a magnifying glass — in the upper right. That action pulls up the keyboard, allowing you to enter a search term in a drop-down window.

5) You can switch from the book you’re reading to another book in your iBooks collection by tapping the Library button in the upper-left-hand corner of the page.

6) You can switch to the table of contents by tapping an icon in the upper left, and then tapping the number of the chapter you want to read.

7) You can tell how far you’ve read two different ways: the iPad calculates the total number of pages in your book and shows at the bottom of each page the number of pages you’ve already read (such as “586 of 2570” with the font set at a large size); and you can see at a glance how far a button has progressed from left to right along a line of dots stretching across the bottom of the page, thus giving you a sense of whether you’re one-quarter or one-third or one-half the way through the book.

8) You can see how many more pages are left to read in each chapter, because, in faint gray type at the lower right, that information appears (“43 pages left in this chapter”).

9) And, of course, you can see the book cover in full color — not to mention any full-color photographs or illustrations the book may contain. And black-and-white photos appear as sharp as on even the most advanced computer screen.

So, why haven’t I trashed my Kindle and switched all my book-reading to the iPad? Here are the drawbacks:

  • I can carry the Kindle with me everywhere. The iPad is too big, too awkward, and just a little too heavy to carry around.
  • Amazon.com still offers by far the world’s biggest selection of electronic books. The company has a virtual monopoly on that market (though that may change over the long run).
  • The iPad has the same annoying tendency that handicapped the Kindle 1: just brush the screen accidentally, and you might turn two pages or ten. (Yes, it’s cool to be able to turn the page with a simple swipe of the finger — but not so cool to find yourself ten pages ahead of yourself without even realizing it until you notice the lack of continuity from the page you were reading to the one that’s come up in front of you.)

So, iPad vs. Kindle — who wins?

They both do. I’m sold on reading electronic books instead of the paper variety.

And I expect I’ll be using both these devices until one or the other of them matches the attractive features of the other, addresses its own drawbacks, and gains access to electronic books offered by all sellers, not just its own in-house stock.
