You say potatoe and I say, er potatoe........so a number of people have been asking for further details on the AX 2009 Role Centres - there's a very nice page on Microsoft.com which takes you through the details of what's in each role. Definitely worth a look:

Also don't forget that a Role Centre Fact Sheet is available for download on PartnerSource, as is the business productivity whitepaper here

Enjoy
