Now that Obama has left the city I can sit down with my Reader again.
Yes, I love my 600 and I use it extensively when I commute to work. December in Norway only means I have to find a seat with good overhear lighting but that is usually no problem.
A great thing with the 600 that I have not seen anybody else comment is that whatever way you hold the device you can always flip out a finger or a thumb to turn the pages. I guess this is not the case with readers where you have to position your hand to be near a button to turn the page. Maybe this is not a problem with other readers, but for the 600 it means you can hold it wherever you find it comfortable on the device.
I have also found it very useful for putting Word documents on that I use with my work, so I can do a quick read when I go on customer visits. The word documents are formatted beautifully with bullet/number lists and everything. When the surroundings are getting to noisy I just plug in my earphones and listen to music while I'm reading.
There are of course lot of things I would have liked to see better, like the gray to be whiter, the PDF's to stay zoomed when turning pages and so on, but all in all it is a great little machine.
