Despite the fact that MacBook Pros were never "pro", I think there will be no more MacBook Pro 13'' in future. I just looked up how much it is to replace the battery of a 13'' and on http://www.apple.com/batteries/replacements.html they don't even talk about "pro" anymore. It's just "aluminium". Is this a change they made recently or was it always like this? For me this would be missleading if I want to change my battery.
