Text reflow is when you zoom in to make the letters bigger, the width of the paragraph you are reading will automatically shrink to fit the size of the screen and the paragraph becomes vertically longer but horizontally shorter. Otherwise, you would have to constantly flick left and right as you try and read every line, since when you zoom in you can only see the section you zoomed in on. A lot of Android devices do this and it can be night and day when it comes to reading comfortably on a small handset and practical by not having to flick constantly left and right for each line. Some sites don't have that nice blog style 600 pixel width and have long widths that even if you zoom out, you will still need to pan left and right. Then there is of course, those with small text that need to be zoomed in anyway. I always thought this was a basic feature on all modern phone browsers. I hope Microsoft isn't pulling an Apple and saying that people don't need it just because they haven't invested in implementing the feature yet. This is probably a bigger deal to me than copy/paste.
