currently using galaxy s..want to upgrade to a new phone.
please recommend me a phone that is having other interface than what's in my current phone.

Budget less than 2.5k.. screen more than 4 inch...looking nice on the outside..sleak design...prefer white actually...some phone i have in mind is samsung note / nexus or maybe 4S...but heard that note is a little too big and lag...4S not much difference with iphone4...so don't know which one to get..

@kae, thinking of changing to note...what do you think?
