I think Harry's character would get a pretty intense overhaul if he had grown up in a normal family. I just feel like so much of his personality is because of how he grew up - second-rate and pretty much marginalized. He has an issue with emotions, in that he overreacts to little things and that he is uncomfortable with others displaying intense emotions (read: Cho crying). Harry would relate to others much more easily and because of that, his friendships may have been a little different. I feel that Ron latched onto him so easily because Ron, too, was marginalized in his gigantic family. He found Harry, even though he was the Boy Who Lived, non-threatening and since he knew nothing about the magical world, Ron could be his guide. If Harry grew up with knowledge of Hogwarts, their friendship may not have started so immediately on the Hogwarts Express -- though I don't doubt they'd eventually make friends since they shared a room forever. Either way, Harry wouldn't be as broody all the time, which would probably make his time in the Tri-Wizard Tournament a little easier, as well as his fifth year. Living with Sirius, he'd be all up in the Order of the Phoenix anyway.
