Yes I did a lot of research on forum and youtube, but I still kept banging my head against the wall so I decided the only way to solve it was to have the iphone 4 and galaxy s2.
I did have a look at the windows phone especially the nokia lumia 800, but I am not that mad to have 3 phones.
I think apple have it in the bag for easy use and its ipod music system, Samsung is great too, I think it is great for those who want more flexibility. So both on par I think.
