Totally agree with you, DrMoze.

Ok. Now we just have to reach concurrence on there being a difference between ePub and ADE.

PRS-700 (and presumably 600) has the same feature. You can also swipe and hold.

I'm afraid it would never occur to me to consider a PDF file to be an eBook, so for me, ADE is synonymous with ePub

IHMO, even between devices using e-ink tech, it's meaningless to compare the speed of page-turn of e-ink device. Major factors affecting the speed are: dimension of screen, e-book format, whether preloading next page is implemented.
Devices with large screen will need more computing power because they are representing more pixels on a screen. So,it's not fair to compare a 6' device with a 10'.
Different e-book formats require different computing power. So, it's not fair to compare a e-book format which is capable of representing compilcate layout to simple txt file.
Finally, if the reader software preload next page in the background, users will feel page-turn much faster. Based on my experience with iLiad, the speed of page-turn can be 5 secs (without preloading) or 2 secs (with preloading). That means, fast page-turning is only the best case, not average case.

Sluggish is sluggish, whether fairly compared or not.

Since you have an iPod Touch, I figure you should be able to seperate them. After all, Stanza doesn't support ADE, but it does support non DRM'd ePub. Ultimately, ADE is simply one implementation of the ePub specification.

Sorry, Bill, let me clarify that. I said that I consider ADE to be synonymous with ePub, not vice versa. I'm very well aware of the fact that there are lots of methods, other than ADE, to read ePub files!

Recognize that ADE is not synonymous with ePub. ADE also includes formats such as pdf and html.

I'm curious about this attitude wrt pdf files. I have read lots of pdf-format ADE books borrowed from the local library. They reflow and resize text quite nicely, and read just like an ebook should on my Reader. And fyi, there are lots of ebooks in pdf format out there, whether or not you "consider" them to be such. Stating that ADE is synonymous with ePub is simply false.

However, it's completely fair from a user experience point of view. When I read a paper book I don't worry about whether it's a DC Absolute (oversize archival quality hardcover comic collection) or a cheap mass market paperback when I turn the page.

Yes, page turn rates are based on more than just the display controller, and may vary significantly on the same device depending on file type, but for the average reader that doesn't matter. What matters to most readers is whether the delay normally bothers them or not.

It's the average that really matters, not the extremes. If it normally feels responsive, but occasionally bogs down, that's one thing: if it normally feels sluggish that's another. Average page turn speed is one of the best ways we have to judge that.

It doesn't have to be a fair benchmark.

Allow me to explain my previous post. I was not asking for a fair comparison. My main point of view is: comparison page-turn speed is meaningless. Pursuing the fastest page-turn device is not a good decision criteria. For example, if a device capable of displaying complicate layout is slower 1 sec than another device only capable of displaying txt file, does that mean the later device match user's needs? It depends. I guess many (or some) users will choose the first device because it can display compilcate layout on screen, and the slowness is in acceptable range.
Of course, page-turn speed is just a parameter, not all. And it's not an important parameter since every device seems to be doing the refresh job in a acceptable, if not satisfied speed.
