Guys the team of Mac Locks (www.maclocks.com) just coming out with a new iPad Cable Lock or iPad Security Cable. It uses a Universal Security Slot.
They came out with a real cool idea of a clear case which is integrated with a slot, so you can use their lock with it or any Universal Kensington or off the shelf product.
No meed for adhesive or bulky solutions:
Apple builds the highest quality products and that has not changed with their keyboard dock. We purchased the keyboard dock directly from apple.com and it came in less than 3 days. The dock is aluminum bodied and has matte white plastic keys. It follows Apple's minimalist design of late featuring low-profile keys with a very responsive feel. It is just as wide as the Apple Bluetooth keyboard. For owners of an Apple Bluetooth keyboard, there is a small difference as the function keys are labeled differently.
