Thank you, Can't wait. I really would like to have the kindle so I can read research papers etc in the sunshine! Need to write mt Thesis next year.
I'm currently writing my thesis too Tulip!
I've tried some papers (pdf format) on my Kindle Touch. I've used papers that contain a wide range of text, graphs and images and I've had no problems. The device displays them in portrait and the user can easily zoom and pan with touch-screen control.
A friend of mine also got a Touch recently and he had trouble with one pdf, specifically with the resizing of the text and lines that made up a table of data, such that it all overlapped when he zoomed. In this case I'd look at formatting the pdf again such that the table is converted to an image, or if that's too awkward or time consuming, I'd just convert the whole document to images rather than text and lines (hope that makes sense). You can download free (and legal) pdf converter software to do this.
For the week I've been playing with it, it seems to me that the device is quite capable of handling most pdfs.
