This ad poster for the iMac is utterly perfect. Perfect photo, perfect slogan (the period at the end is key — “Yum” without the period wouldn’t quite play the same way), perfect relative scale and placement of the elements. Even the kerning is perfect — Apple Garamond never looked better or more timeless.
@gruber But not “Think Differently”?
@marxy @gruber That improves nothing

@villasbc @marxy This was much-discussed at the time. “Think Different” is infinitely better as a slogan. "Think Different" is great; "Think Differently" would be dreadful.

Think Different both sounds better, and conveys both *what* to think and *how* to think.

@gruber @villasbc @marxy Yes, apart from any discussions on “grammaticality”, slogans and headlines are not subject to the same rules as running text. Reading flow is not as important.
