Hi everyone,
the cover arrived, and I quite like it. The fit is as good as any I have seen, and it adds a touch of class to the IQ that its sleeve seemed to lack.
That said, the sleeve is more generous in its protection: the cover is light and the spine (where the front folds over the "pocket" that holds the IQ) is thin and soft. I don't think this is a negative in terms of durability, because I am confident it will last for several years, or what I see as the projected life of the IQ.
Lightness is a plus for my wife, who has a phobia of things heavy. (Massophobia?

At university, she sat next to me in class not because of my dashing countenance or rapier wit, but because the maths text was far to weighty for her to carry to class...)
The clasp works well, and the little pockets inside the cover will no doubt prove useful at some stage, though they will not hold, say a USB cord.
I'd rate it an 8 out of 10 for both quality and value; by comparison I'd give the Pocketgoods covers a 9.5. So, I'm pleased to have got it, or at least, my wife is.
Any other questions, please give a yell.
Michael P
