Kindle

Our group travel about quite a bit. I attend several meetings with material (70-80 pages) that consume piles of dead trees. So I've got a Kindle to try and improve our lot. First impressions are good. Screen is very readable even in direct sunlight. I've tended to use PDF files for work and OU documents and they display well.
On A4 if there's a lot of text or formulae then rotating text by 90 degrees helps. Zooming and panning on PDFs has apparently improved over past Kindles but still a bit clumsy when dealing with say 3-column scientific papers. A way out might be a utility to repaginate such docs as single column PDFs (Does anyone know of such a beast?)
Wifi works quite well. Keyboard isn't designed for a lot of input but is usable. Browser (WebKit based) is Ok but no flash (so no YouTube/Iplayer - but e-paper refresh not really suited to video playback anyway (at the moment)), no support for multiple windows, I've had no joy at getting it to render local (i.e. on Kindle) HTML files and it won't allow you to download PDFs direct from web-sites (so you need to download from PC and then copy to Kindle i.e. almost Sneakernet).
However, these minor things withstanding, it is a useful device.
