Not the OP, but I noticed the same and in my case the reason it's simple: I have all my email/attachments since 2004/2005 in gmail. I use full archive search way more often than I care to admit.
I love how gmail works/syncs across all platforms (my iPad on iOS, two Android devices, PC laptop and Mac desktop) and doesn't limit me to the Mac/iOS platform.
