I realized after installing iOS5 on my iPad and iPhone that my iWorks apps (Pages and Numbers) are backing on iCloud any document I create on my iDevices. More than that, iCloud will sync those documents between my devices... Then it hit me: that means that I can create a spreadsheet in Numbers to track my tasks or todo list and that list would be updated on my iPad and iPhone automatically. There are tons of todo apps or project management apps in the app store. But a spreadsheet often does a quicker and better job for stuff that you don't need a multi-user access. So with this new feature: - I can manage my tasks - I can update my project time spreadsheet - I can have a document to keep notes and comments - I can manage my expenses - etc... Fully customizable, easy to share or send a copy to someone else and available on my iPad and iPhone. If I had a Mac, it would also be available on it... No worries about forgetting a copy, or not having access when network is not available... Cost me 20$ for Pages and Numbers. It's worth it considering I no longer have find the perfect apps for my professional life. iWorks is now perfect! VicoPad addict!
