To help you create your own eMail attachments, Apple is offering a cradle for the iPad that is attached to a full size keyboard. Yes, you read that right, you can now burn through your work when at the desk and then drop the size down to just the iPad by lifting it out and head down the hall. No mouse, yet… you will still be using your finger. That’s fine, the keyboard is a huge jump, we’re excited!
