In what should be one of those no-brainer decisions, the developers behind Mailbox have plans to bring the app to iPad, with desktop and Android clients not far behind, TechCrunch reports. There is no ETA on a desktop version, Mailbox developers tweeted, but it did confirm that the iPad version is in development.
Mailbox did away with its reservation system last week, the first key step in expanding to the iPad and other platforms. While the app initially gained a lot of users, expanding beyond the iPhone is imperative for users to keep using it. It was one of the key criticisms TUAW staffers had when we reviewed Mailbox collectively, and my stint with Mailbox lasted a couple days until I realized that Mailbox just couldn't integrate with my workflow as long as it remained iPhone-only.
