More Tweeps for iPad mockups

I previously posted some mockups of an iPad edition of Tweeps, my new iPhone OS app to easily manage Twitter accounts.

But as I said, I've been struggling with coming up with a satisfactory design. My latest thought is that I shouldn't try to emulate a physical object like a notepad or book, but would be better following Apple's example with apps like Mail, and use a split view.

So here are my latest design mockups (again done in OmniGraffle).

In landscape orientation, a split view shows a list of pages on the left, and the details on the right; in this case, the main Profile page for your own account (click to see full-sized):

In portrait, the left view appears in a "popover" instead:

I'm not sure if the Edit button should be in the left or right views... but there's more room in the right, so that seems reasonable.

Here's a sample of the Following page in landscape:

What do you think? I think this is a better design, more clean and consistent — and allows me to use much the same color theme as on the iPhone, as a minor bonus.
