As I said in my own review, Mailbox helps me get rid of all the unimportant stuff before I even sit down at my computer. I’ve described Mailbox as a complement to the inbox, not a replacement, and that continues to be true. I still log into Gmail when I need to compose a message or search for an invoice, but otherwise I flick through and browse notifications and messages when I’m away from my laptop or PC.
Mailbox on the iPad doesn’t offer any distinct advantage over its iPhone counterpart, the app being the same right down to the compose view. Oddly, Mailbox is locked to the landscape orientation, meaning that your email messages can only be viewed in half the space next to the sidebar. My guess is Orchestra felt that seeing the big picture — the entirety of the inbox — would be better for previewing and triaging email over opening individual messages as you’d have to in the portrait orientation.
