I would not agree that Inbox attempts to "hold your hand". What Inbox attempts to do is achieve a greater level of functionality by automating the capture and processing of information that's already on your system and brings it into an environment where you can process it and associate Actions with it, as opposed to having to re-enter it. This information comes from Mail, iCal, and your desktop.
Why do you have to re-enter or manipulate information that is already on your system? No other program that I've seen for the Mac makes use of the information already residing on your system whether it be OF, Things, or others. Although there is a bit of rigidity with Inbox, it does not require you to re-enter or manipulate information.
For example, with Things, if you have an email from which you want to create an Action, you have to drag the email TWICE to Things (the first time it does not work but the second time it does, which has been a known issue in all of the beta versions and continues to be the case with the current "release candidate") and then you have to enter the subject, the category/area, etc. Instead, Inbox does a scan of Mail and then you decide whether you want to deal with it right away, to associate it with a task, or to do nothing!
I admit that Inbox is still a bit quirky and I would say clunky and rigid with some things. However, it's the only one that does the "looking for" and capturing of information into an interface from which you can formulate an Action rather than having you formulate an Action and then have to go looking for the information/file/email to associate with the Action (e.g. with Things). In essence, Inbox brings the information to you for your consideration.
I do know that there is supposed to be a new version 2 coming out, which I hope will deal with some of the "clunkiness," but there is no release date and no beta version available yet.
Let's hope that it's sooner rather than later . . . .
