For phone itself: Since I am not interested in the latest Samsung / Apple spending spree tour, I wanted a phone that is both functional and robust and is unobtrusive beautifully. The Xperia Go has all these properties, is also waterproof (multiple getest) and largely shockproof (also getest: /). The shell and caps are interchangeable, but relatively expensive if you buy them from Sony. The glass has in me a few micro scratches but that because of my rather harsh handling! In addition, it fits comfortably in your hand (no mini tablet), and can be very fluid use and even with wet hands! Sumasumarum a really nice, good quality phone that will be thwarted only by bloatware, but otherwise definitely his money's worth!
