I have an Id from 2005, and while it's going strong, I loved the updates to the new one, be it the simple design changes to the water bottle holder + cell phone pockets. And I really had my eye on the navy variant of it.
The product page says its on backorder in all colors... but it doesn't come up when I look for messenger bags, I have to specifically search for it. This makes me nervous that it's not coming back! Is it? And in multiple colors?
Also very sad the Imago retired. I have one in navy/cork and it's my everyday bag. People often ask about it, but now I can't tell them where to buy it! Alas it won't fit the 15 rMBP, so I'm looking to upgrade the id =)
