Why migrate from Access to MySQL?

[Paul DuBois]

Suppose I am a Microsoft Access user and you are a MySQL advocate.

What reasons would you put forth to convince me to migrate
my tables from Access to MySQL?  (Either for partial migration
where I still use Access as a front end to the MySQL server, or
full migration such that I switch not only to the MySQL server
but to MySQL clients as well.)  Thanks.

Sorry for the crosspost, I'm trying to hit the Windows users
on the MySQL lists.
