I can't remember ever having been stunned by a logo.

The height of my experiences could be described as:

"Oh, nice logo." or "Hmm, clever."

The line between "clever" and "trying too hard to be clever" is also quite fine.

Some logos become iconic, but that has as much to do with the brand itself as with the logo. Even if Microsoft had the Nike logo, it would still be uncool.
