Microsoft would be the obvious company to release one, and rumor has it the app has been finished some time, but they are currently opting to push their Surface tablets as the only viable Office tablet option instead. Apple have their iWork suite which isn't half bad, but the constant converting between the formats can't be the optimal solution. We need something that can natively work with the MS Office file formats. Then we have a few others who gave it a shot (Quick Office, Docs 2 Go, etc.), but let's be honest, they're rather useless for anything that goes beyond VERY casual work. Looking at the Mac and PC world, we have Open Office and various spin-offs (Neo, Libre...), that provide very good and usable alternatives to MS Office. My question is, where is the "Open Office" for iOS? What is the big challenge that prevents this from happening? Hardware constraints? Coding structure of the platform? I have seen some truly impressive apps pulled off on the iPad, so I have a hard time believing this is the case. Anyone here have some knowledge on the matter and can provide some insight?
