The Class 10 prowess actually shows.
Combined with the dual-core goodness of Galaxy S2, it actually gave a better score on the AnTutu Benchmark(6118: Better than Galaxy Nexus :P) with the storage set to the card rather than the phone's internal storage.

Disappointed by the look and the feel of the material. It feels cheap to hold and work on. The graphite in the picture does not, in anyway, match to the dull and pale grey-ish color of the case. Also, the material is so thick, that the phone has lost its sleekness. Doesn't qualify to be a worthy case for a 30k phone.
Flipkart's delivery system was impressive though. The package reached me just one day after the order.
