Yep...it sure does with people who need to type the domain name in...they either forget the hyphens or they type in underlines instead. Sometimes they just forget where/how many hyphens are in the name.

Haven't noticed any difference as far as search engines.

Hyphenated names are usually slightly lower in appraisal $value because of the hyphens.

Anyway, that's been my experience with them so I avoid them any more and use the hyphenated ones I have for group/division names , where I have other domains under a main one, so I eliminate the people mis-typing it problem. HTH
