ACROSS THE PLATFORM: TechCrunch reports that SF-based Inkling, which built its brand around interactive textbooks for the iPad, will start serving up e-books for the iPhone (at no additional charge). The move makes sense given that there are four iPhone users for every individual on the iPad, according to CEO Matt MacInnis. As one may expect, retaining quality interactive features on a smaller screen was the primary challenge, but the video promises a fairly seamless experience. (MacInnis also shares thoughts on the digital publishing landscape--particularly why the company is the only "accurate contrarian theorist" daring enough to re-inventing the publishing process.) The two-year-old startup boasts users at over 4,000 schools, including and half of all medical schools in the U.S.
