The definition of a great logo is a logo that is: dominant, memorable, well designed and above all easy to remember. Top of mind comes the Nike "Swoosh"., it is effective through its simplicity.
well, i'd say , SonyEricsson, Nike & specially SONY; the SONY font is very attached to the brand that the 1st thing that comes to my mind when looking at any other logo in the same font is automatically SONY!
