Permanent is touch office software, starting with the spreadsheet. The office software market is one of the largest software markets there is, at over $24B/annually, and the rapid adoption of mobile devices is driving demand for a viable touch option. Touch interfaces are radically different from mouse interfaces. Copying old interfaces doesn't work. Consumers are waiting for a tablet spreadsheet that gets touch interaction right, and Permanent is the first spreadsheet on the market to focus on interaction design.
