Review extract:
A year or so ago, you knew where you were with a Nokia S60 smartphone - it would be about a certain size and be a 'candy bar', with later models even foregoing a wacky keypad design. Since then, we've had the 'transforming' N90, the gullwing E70 and the thumb-keyboarded, wide-screened E61, to name but three. The N71, then, doesn't come as so much of a shock.
I was going to write about this being Nokia's first S60 clamshell device, but then I remembered the 6260. And the N90 itself, each of which could be configured in clamshell mode. But this is a true clamshell, in that it can only be used in this one form factor. As with other clamshells, there's the advantage of more screen and keypad real estate, and a better position during calls, at the expense of slightly greater thickness and (probably) fragility.

Side by side with the older 6260, plus the 6670 and N70.
