Can't post a review in iTunes so here it is
The application appears as iDisk on the iPhone or iPod Touch. In the store it is called MobileMe iDisk and can be found
here.
I have downloaded the application and am presently running version 1.0 (96). I have been using
Air Sharing since it was released but I use iDisk quite often to back up documents, have access to Office and iWork documents on the go, share files privately and use the public folder when posting items to forums. That being said here is my immediate reaction to Apple's new application. I have been waiting for this with baited breath.
MobileMe iDisk continues the legacy of keeping things simple yet elegant. The application stores recently viewed files (up to 200 MB collectively) locally on the iPhone/iPod Touch except for audio and visual files which are streamed. If you have a slow connection you will have issues with the streaming just like any other audio/visual source (don't blame Apple). Layout of files is similar to the Finder in your favorite OS X. You do have some options, as in the Finder, to show extensions and system folders. I have not discovered where the files are kept locally. Knowing should make it easier to delete local files, especially if they contain confidential information.
Files and folders take just a moment to load the first time but once they have been opened they are very quick to browse. The "Recents" button on the bottom of the window to recall, well, recently viewed items is especially useful until a time comes that multiple files can be held open at one time.
The language under the "Shared Files" icon is confusing as it implies that any file can be shared. An icon appears to the right of the file name to show that it can be shared. I presently am able to share files in my public folder and documents folder. Sharing constitutes emailing a link to the file.
The "Public Folders" icon at the bottom of the screen is for your subscriptions or access to other members public folders, not your own.
There is no access to the Backup, Site, Software or Web folders
Animated GIFs do not work.
Interactive QuickTime games/video do not work.
You do not have direct access to MobileMe features beyond folders (same as in the Finder).
Documents are viewed as standard pages, not as a single long page (fine by me).
The 3.0 copy feature works but live editing does not seem to be an option.
No option to transfer files from folder to folder, folder to computer, or iPhone/iPod Touch to computer (this comes in handy when giving a lecture and the file needs to be transfered to the local computersometimes PCs just don't understand how simple things could be).
MobileMe iDisk has few preferences (again, fine by me) so the interface is clean and uncluttered. I do think the option to clean out the cache or downloaded files either for space, irregular behavior, or security should be available.
Overall, I like it. With an update or two it will achieve five star status.
