CONFIRM: yes the case in the picture looks like the Terrapin case, $5.95 at Amazon. i have the black and purple versions for my TMo 925, also comes in red and pink. black has been my daily driver. it's a nice clean minimalist look, which i like with the 925 as the phone seems just too attractive to bulk up. provides nice access to all of the buttons and ports. does it protect it enough? don't know, havent dropped it yet
i also bought the Nillkin V Style Mix Flip Pu Leather Cover Pc Hard Case for Nokia Lumia 925 at Amazon which is an attached back with a flip front. conceals the phone a lot more but looks very nice. again, didnt like covering up the phone so much. also i found the camera is easier to use without the flip case.
the Incipio cases look nice also, especially the feather version. just put feather cases on 2 Lumia 521's for my parents - thumbs up. not really fair that a case for an $80 521 costs $20 while a comparable case for a $750 iPhone 5s costs $8 tho...
agree the case market for the 925 seems barren, especially for premium options...hopefully will improve over time. could we get a Magpul field case? if it's any consolation the case market for the 521 is even worse because of the extra 4mm from the 520
