I've had two Nillkin cases and a PDair and none seem to suit me (I don't know why).
I had the Nillkin hard shell but I gave that to someone at work who had one of the cheap s-line cases.
Problem I have is the phone lives in my trouser pockets and with the job I do it needs some good protection but I worry about the screen with the Nillkins and the PDair is too bulky.
I've seen a Krussel SlimCover
that's on preorder with Expansys
. Hopefully it'll be out soon.
I have the PDair book style in black leather and a Nillkin gel case in grey/frosted.
If anyone wants either of them let me know (say £15 for the PDair and £5 for the Nillkin delivered to UK and maybe anywhere else depeneding on price?)
