Which new Yahoo e-mail should I choose?

I'm on Original now, but Yahoo is making us all switch in July 2013.

When I try to click into Mail now, what comes up is a "plea" from Yahoo to switch. They are giving me a choice of Full Featured (Recommended) or Basic, but do not spell out the advantages of each.

Does Yahoo have a site giving details on the 2 plans? Right now I think I would only need Basic as I use e-mail only to Receive, Reply and Send. Not computer savvy so don't know how to send pictures as attachments and all that other good stuff you Techies can do.

I know Yahoo monitors Answers. Can you direct me to correct site for info.

Also, those who have switched - how's that working out for you?

Thanks.
