POCO Benefits:

Technology Agnosticism is a bliss: This concept is usually revolving around PI (Persistence Ignorance), but it is not only that. Persistence Ignorance means that your entities should be cleared of any persistence related code constraints that a framework - usually an ORM - forces on you. This is, for e.g. if you have attribute level mapping where those attributes are not part of your domain but are there just because some framework wants them to be there, then your domain is not persistence ignorant.
