Clearly the iPad is already great for consumption and fun, with some creation, but I would love to see the iPad reach a point where you truly can leave the laptop at home and get 95% of your work done on it. I haven't even purchased my iPad yet and it already seems like those holes are getting filled fast. OS 4.0 will obviously take care of multitasking. It might also improve file sharing but we'll see. I'm seeing mention that you can already specify a "viewer" app for file types on iPad (but I don't know how this works) theoretically allowing you to get an email with a Word attachment and open it in Documents to Go or whatever app you want, rather than the built-in file viewer. iWork for iPad isn't very fluent with Office files. It may get better over time. Browsing the iPad section of the App Store, I see Office2 Pro which implies that it does better - looks rough but may become a great alternative over time. I fully expect Documents to Go to end up with an iPad version as well. Heck, maybe even Office will come some day - it's on the Mac after all. I don't need all Office functionality but I need an app that won't mess up existing formatting in a document emailed to me. I also see FileBrowser in the iPad app store. It's called NetPortal on the iPhone but looks almost the same. It gives you access to remote server files, downloading, opening and editing, and attaching to email. That will go a long way to making my iPad work-worthy. So we're getting there. I'm convinced owning the iPad will definitely be worth it and this will only be more true over time, as apps are released and the OS is updated.
