Interesting...almost everyone of you who said reflow is great on the 650 immediately follows that up with a list of caveats that prove reflow sucks. Get an iPad, tablet, or Netbook for the best experience, and forget about eInk with PDFs because MUCH sooner than later the eInk reader will terribly disappoint you. It is easier to launch the Space Shuttle than to modify/create PDFs that look GREAT on an eInk reader!
