Popular wisdom has it that tablets are great for consuming content but aren’t that useful for creating it. Don’t tell that to Josh Leong, though. His Y Combinator-backed startup, Grid, is based around the idea that a tablet should be a great place for spreadsheets. Indeed, as Leong told me earlier this week, his idea is to reinvent the spreadsheet around touch, all the tools and sensors available on mobile devices like the iPhone and iPad, and the way normal people (as opposed to Excel power users) actually use them.
Grid is launching in beta for iPhone and iPad today and you can sign up for an invite here. There are still some features missing in this beta, but you can already use Grid’s collaboration tools and get a feel for its ingenious “Maestro” user interface.
