Satchel is Backpack on the iPhone done right (finally) according to The Unofficial Apple Weblog.
Whenever I'm evaluating a client application that interacts with a web-based service via its API, my acid test is the answer to this question: "Could I fully utilize this service using only this application?". Satchel gets you most of the way there. With existing Backpack pages, you can view all of your notes and lists, edit the pages tags and even view attached images and files. You can also create new pages, but the API doesn't allow for creating anything other than Note and List elements within your new page (though, you can email files, etc. directly to it once it's created). The good news is, Satchel also has a "send an email to this page" button, so you can add content to your new page relatively easily. The Satchel crew also really spent some time on the list interface, making it easy to add, remove and reorder list items in a very iPhone-ish way...While you may be a little hesitant to drop the $9.99US on this one, I can say that it's worth every penny for the true Backpack fanatic. It's gone a long way to removing the barrier for those looking to embrace Backpack as a service, but feeling a little hamstrung by the lack of a decent mobile interface. If you love Backpack, you'll love Satchel [App Store].
