I would not comment on the technological part superflux everything is already said by others happy owners of this phone bomb. I went from an iphone to jewelry and frankly no regrets and especially the contrary I feel revived without itunes. A very easy grip, outlook sync (contacts and calendar) smoothly with kies what I feared the most and quickly reassured. So to buy without hesitation especially if like me you use it in the context of work frankly using the pen is really a meeting in happiness)
