How do you know what you "like" if you dont try it out? Windows Mobile works fine, same as android same as iOS all share same basic function and have roughly same possibilitys. Personal taste/brand preferences or needs decide and yes one of them is how your phone looks.
You mean samsung note ? A samsung S3 is barely any bigger then an iphone let alone the new one.
And I for one wont buy another iphone if it hasnt got a least a 4" screen. Not everyone has the fingers/hands of a 12 year old or wear skinny jeans .
Btw its funny how you say nobody cares how your phone looks but then you do care how they look.
