Today my brother asked me how he could access his MobileMe iDisk now that he had upgraded to iCloud. I told him that he should just look in this Finder, without realizing that iDisk is gone for many MobileMe users who've migrated over to iCloud. However, there's still a way to get to your iDisk (at least, until Apple pulls the plug on MobileMe for good next year!):

• Open Finder and press ⌘K (Command + K)
• Enter 'https://idisk.me.com/yourMobileMeName' as the Server Address (without the quotes)
• Click the Connect button

Your iDisk should mount in the Finder, although it may ask you for your MobileMe password first, if it isn't saved to your Keychain.
