I'd love to play with a powerful Lua-enabled spreadsheet on the iPad, but the pricing is miles off. It's NZD 13.99, the same as the Apple productivity apps and Photoshop, but that price is apparently a 50% discount and the app looks a long way from finished. At NZD 4.99 I'd buy it and start playing without thinking twice.
