Apparently the Shades of Grey is available in 'flipback' format. Does anyone have any experience with this format?

I just ordered one, and I hope to receive it before I leave on holidays in a couple of weeks. It looks like it's just the right size to slip unobtrusively in a pocket.

It's been about a year since I last bought a paper book, but my kindle is on the blink, and I won't receive the new 'paperwhite' for another couple of weeks, so I figured I might as well give the format a chance.

It is certainly small, but not the easiest format to read.

I received it the last week, but haven't taken the time to read it yet.

I ordered from the Goliath Corporation, and it's amazing how these huge multinationals work. Much cleaner and nicer than the cloying familiarity of Amazon and the like.

I received a new kindle (paperwhite) at the same time, and I must say that in may ways I actually prefer reading on that. But the flipback book appears to work just as advertised. Page turning is even faster than on the kindle, and the contrast is higher. The drawback is that there's no backlight, but at the same time the battery life is unbeatable.

I was a bit surprised at the font though. The font used here is Fedra sans, or something very similar to it:

I have to wonder if this was chosen specifically for the flipback, to give increased legibility at reduced size, or if someone (at Hodder?) decided that 'sci-fi' needs a futuristic font.
