These Apple power supplies come with a cord to replace the little block. Swap, done. No odd hanging mass from the wall; I get to choose where the brick lies.
Perhaps this Blockhead is a convenience item, but not at $20. Not even at $35 for two.
Only 19.95 ex shipping for a little plastic block! How cheap! I can't wait for them to release the improved Blockhead-S this fall, which will be so much better!
$20? Seriously? This could be produced for less than a nickel
Personally I just bought a figure 8 cable for a pound.
This is actually pretty cool—just not at that price.
