A while back I was sent the original Ztylus to review. My only real complaint was that it was too thick. Fast forward to today, when I received the new Slim model. They have done so much more than just put it on a diet! Check out the video for starters: It now comes in two color choices: black and silver. I got silver. It looks and feels very similar to the aluminum of my MBA. The thickness is now perfect. It's barely larger than the Pencil itself. Oh! And they added a regular pen clip! So now you can clip it to your case, your pocket, or the pencil pocket of your purse. Oh! And the added a little gadget that keeps your Pencil cap from getting lost when your charging. This is now a must-have accessory.
