Sorry if this has been brought up before but it's near time for my dot Mac subscription to be renewed and I see multiple versions of dot Mac lingering around the web. Verison 3.0-5.0 and I just wanted to know is there any difference. I could save a little cash if I got one of the older ones but I don't want to lose features. I called Apple this evening and their sales rep said that that the latest version offers the 10GB storage. I'm not buying his answer because I currently get that now so I can't see renewing a subscription would give me less space. Anyone with experience buying dot Mac?
