Some users in SharePoint 2010 don't have links in the upper right hand drop down menu for MySite or MyProfile.
In Central Admin I have MySite set to allow Read and Create for All Users (Windows) and All Authenticated Users. All of the users, including the ones missing the links are able to login and access most other SharePoint content and resources. I am able to view the MySite and Profile pages of the users missing the links in the menu.
I'm guessing that something is security trimming the drop down menu for some users. I just can't find anything that stands out outside of the UserProfile Service Application and MySite configuration that I've already done.
