I was wrong earlier when I said that you can't return books borrowed from the library using the T2. It turns out that you just have to go to the Shelves section and long-press the borrowed book, and there is a menu selection to return the book. I've tested it a couple times now and it works fine. So the Tolino Page has nothing over the Sony PRS-T2 in this regard. Both can be used to borrow from Overdrive (if you you the patience to use their S-L-O-W browsers) and both can return the book directly from the device.
I should say, this works with Overdrive when using the Fort Worth Public Library. It's possible that other libraries have different login protocols that I don't know about that could keep the T2 from downloading (or logging in). No matter what I do, I can't get the T1 to "unpack" borrowed books. It always returns an error (though it does let me login to the library and borrow the books, it won't "authenticate" them, or whatever it's called when ADE doesn't work).
