The other touch buttons on the lower screen offered choices for fixing Nook settings or for reading a book for free in-store via Wi-Fi for an hour. At the store where I had the demo, there were several free-reading choices, including a popular new book on wines.
Adjusting the font size took a surprisingly long time. Twice, moving from large to very large font size took at least 10 seconds, but that may be because the Nook was adjusting the entire book all at once. By comparison, this font-adjusting function takes much less time on an iPod Touch, where I bumped up the font size to read a play by Shakespeare, which I've done several times.
In fact, response times generally seemed slow, including responses to button pushes for page turns when using the arrow buttons outside the upper 6-inch diameter gray-scale screen. Touches on the lower 3.5-inch color touchscreen were very responsive in bringing up a page on that screen, but were slower when I used it to get a response on the upper screen. For example, if I highlighted on the upper screen that I wanted to open The Financial Times by navigating via the lower screen, waiting for the refresh on the upper screen could take a moment, which was off-putting.
Several early reviewers have also noted such delays. Specifically, Engadget's reviewer complained that "you have to get used to all kinds of little pauses and punctuations in the experience," and maybe that's the crux of the problem. In essence, you have to train yourself to get used to the pauses -- and to use two screens to get one result. This might be similar to using two monitors on your desktop run by a single computer.
If Apple really does produce a tablet that includes a multi-touch interface as well as clean, clear e-reader text, I hope it can carry forward the responsiveness of the touch found in its smaller devices.
The Nook also provides a single 14-day lending period per book, which will interest many people. However, it might be more important that the Nook is working with the relatively open epub format for getting access to books. (It is not totally DRM-free, however, depending on the publisher or writer.)
While shipments of the Nook have been delayed, I will resist the urge to become an early adopter and instead assess the market more fully for upcoming devices. I'm excited by the e-reader concept generally, but will need to ask myself what I plan to read most often in digital format on a portable device: Will I want to read newspapers more than novels? Or perhaps the occasional IT textbook or technical journal? I fear a single e-reader won't do it all, and that could get expensive.
In general, the market for e-readers is still young. I'm a careful buyer; I'm waiting for an e-reader that is better designed to read many kinds of materials easily and efficiently.
