The notion of not having a visible file system for is great – for 90% of tasks it really simplifies how users interact with the device, and makes for a streamlined experience. However, there are several very important instances where the inability to access and use a traditional file manager really limits the iPad. These include the ability to manipulate documents using multiple applications, 'save' files from the web for later use, transfer files between devices/servers (including uploading files) This crucial 10% is the difference between the iPad as a very cool gadget, and the iPad as a viable replacement for a netbook. Obviously adding a file manager given the current setup will be a challenge, but I see no reason why a very simplified version of 'Finder' shouldn't be possible. 'Documents' folders, behind a Finder icon, would add a ton of functionality without affecting the primacy of individual apps as the primary means of document interaction! So, what are the chances we'll see this from Apple? And what are my current 3rd party options?
