With the WiFi iPads shipping for delivery in less than a week, I thought we should update you on our status.

Today (March 27) is the last day to submit apps to the App Store and be guaranteed they’ll be available on the iPad App Store on its official release date (April 3). For a while that was our goal, but as time went on we realized it would be in everyone’s best interest if we had a chance to see what PocketBible looked like on the actual hardware. The emulator we run on our Macs is good, but it’s not the real hardware. We’re concerned about performance and simple things like the usability of the user interface, given that we can’t really tell how big our buttons are or what it’s going to “feel” like on a real device until we have one in our hands.

So, we won’t release a product to the App Store until we have a chance to see it running on real hardware. So that means sometime after April 3.

The great thing about the iPad is that it runs our iPhone code pretty much as-is. The bad thing is that it runs our iPhone code as-is. The experience of running an iPhone app on the iPad will be less than optimum, but it at least will give the iPad a couple hundred thousand apps on day one. Ideally, every iPhone developer will be customizing their apps for the iPad, and that’s what we’ve been doing.

While the iPad is a mobile device, it has the screen real estate of a desktop or laptop device (1024 x 768). That means while we’re using our iPhone code as a base, we have to think like we’re developing for the desktop. Not a desktop computer with a mouse and a real keyboard, though, but a desktop computer you operate with your fingers and type on a pop-up keyboard. So the interface is an interesting intersection of desktop and mobile paradigms.

So what will be new or different on the iPad? First, You’ll have plenty of space on the screen for some controls to be present all the time, just like on your desktop where menus and toolbars are generally always there. This makes it easier and more intuitive to get around.

Second, the bigger screen means there’s room to split the screen and show you more than one book at a time if you want.

Third, we’ve taken advantage of this opportunity to add a frequently requested feature: The ability to search your entire library at one time. The larger screen means there’s room to give you both a search results browser and a library browser at the same time. We think this is going to be a great addition to the program.

Finally, you can expect changes to how you open books and navigate within books. It should take fewer touches to find your way around your library.

We’ll post some more details as we get closer to releasing the product. With the actual release of the iPad itself coming up, we just wanted to give you some advance notice of what’s coming. We think you’re going to like it.
