I have been owning Nooks for the past 2 years, and when someone asked me that they wanted a reading device, I recommended them a Kindle, becuase I saw many reviews online saying that this device has really improved and is in many ways better than a Nook.
But oh horror! WHERE THE HELL IS THE REFLOW?! And how the hell can an e-book reading device be called "good" if it doesn't have reflow? This, without any exaggeration, is pretty much one of the most important features!
The person I recommended this reader to, called me complaining that they are trying to read a Russian book and the text is too small. Just increase the font I said, and you are good to go! The reply was that now the page is cut off and the have to scroll horizontally to see the other half... WHAT?! I thought my friend was just being stupid, so I said I'll come over and help them out. But I quickly found out that unfortunately they were right!
I also found out that I couldn't jump to a certain page in a PDF document. When I selected "Go To" nothign would happen...
No worries I said. PDF is probably not the best format for this thing.. We'll try... EPUB!! It works great on my Nook!
WTF?! EPUB is not supported?!

I have to use converters? And if I want reflow I have to email files to Amazon?! Are you kidding me? We are talking about a 60 year old man here... He doesn't know how to deal with this shit... I should have recommended him a Nook..
Now off course the standard reply would be... "You should have done your homework before recommending anything to anyone!" But with all the positive reviews it was hard to see through the BS. Virtually EVERY ebook reader supports reflow and many support EPUB! I wonder if the new Kindle Touch is also crippled in the same horrible way, and if it is so, I would have to wonder how anyone in their right mind would buy this device over the Nook...
The ONLY nice thing I noticed about the Kindle is the fact that, for technical PDFs, it is nice to be able to scroll horizontally through the graphics/pictures on the page.. But then it is also necessary to enable reflow when needed.
Lets put it this way... Kindle is a MAC. And Nook is PC. Nuff said.
