I have been using the Samsung galaxy Y S360 for over a year now and it is one of the buys in the gamut of smart phones. The phone is a pocket dynamite with a plethora of features that I actually wonder whether Samsung had gone bonkers while quoting its price.
Guys with smart phones priced at 10-15k phones might feel the pinch on their wallets when buying their phones but with Samsung Galaxy Y, its all pleasure and no pain. The multimedia features, sound quality, the display are more than good enough.
The one slightest problem might be when you plan to use Wi-Fi or GPRS for a long time, the battery might give in a bit sooner than most other smartphones. But hey, at ~6K, you cant ask for more.
