with the SG2 in question, performance-wise it is great. Very fast and beautiful screen. However in terms of games, you can dl some RPG with great grafic however the SG2 is only capable of playing it for about 15mins then it overheats and shuts down(...) In terms of size, I think it is too big + "too" slim which makes it uncomfortable to hold. Beyond 4,3inch screen will probably just annoy me. p.s. I don have an SG2 but one of my friends have it and he is very excited (not the overheating part however ) the battery time is also a major issue. He can't manage it to get above 12h even though he has task-killers ect (but then you loose the multitasking)
