Question K3 or PRS-650 for PDF viewing?

Hi,

I know that both devices are not optimised for PDF viewing and require zooming and panning to read PDFs. However, I have a question to the people who have been able to try both devices: which one is the best for PDF viewing in term of interface?

Many thanks in advance.

For viewing PDFs you should get Kindle DX or another device that has at least 8-inch screen. If you have to choose from 6-inch readers, then probably Sony PRS-650 is better because it supports multicolumn mode for PDFs. But that won't help you if your PDF files have single column layout. As for panning, forget about it, e-Ink is too slow for that. I am currently working on a program that would allow reflow of complex pdfs for 6-inch devices, but it is not ready yet and it probably won't be able handle all of the complex pdfs, because there are too many page layouts and designs. Existing tools for PDF conversion and reflow are not very good. So I would seriously consider an ereader with a screen larger than 6 inches.

Are the pdf's mainly text? If that is the case the sony readers will allow you to reflow the text to fit the screen. The kindle 3 does not do that. I have a sony 350 and a kindle 3, and pdf is far better on the sony. That being said, if it is just a txt pdf, I can convert it to mobi using mobipocket creator and it looks great on the kindle. The problem is, I have a lot of pdfs, hence having two readers.

If there are a lot of charts and graphs in your pdf files, go with something larger like the Kindle DX or the Sony larger version.

Of those two device, the Sony is better because, as stated, it supports reflow; the Kindle does not.

Does Sony support PDF links? (Kindle does not)

Also how do annotation features compare?

Many thanks for your answers and advice.

Unfortunately, the DX is not distributed in the UK, and is too pricey for me.
Regarding the choice between a K3 and the Sony, it is a dilemma. I will not read only PDFs, so it is not crucial. Furthermore the network capability of the Kindle makes it very interesting, although I will not buy DRM books by principle (but the wireles has other useful usage than buying through Amazon).

How the reflow makes PDF reading so much better? I looked at the pictures side by side of the two devices, and it was not clear to me the PDF on the Kindle was not readable. Are there other reasons, such as the zooming and page navigation handling? I mean is it easier to change columns in the Sony that is not practical with the K3?

Thanks.

Regarding reflow, you can get the flavor of this using Adobe Reader to look at a given PDF. It has a Reflow mode. From the little I have played with it, it is not something you can count on to improve small screen reading of PDFs. Sometimes it works okay (with simple text layout), but some PDFs I tried would not reflow at all, and others turned to mush.

So while it is probably a good option to have (and hopefully Amazon will add this feature at some point), its effectiveness will depend on the PDFs you attempt to use it on.
