There has been some complaining on twitter about it being December and the the new Mac Pro still not being for sale. Since I still have the source to Is WWDC Sold Out Yet lying around, I put it to good use and created
Can I Buy a New Mac Pro Yet? Update: The new Mac Pro is available, so the toy heroku instance has been deleted.
Cibanmpy is functionally the same as Iwsoy. It accepts an email address, and after confirmation adds it to a mailing list that will send one email when Apple adds a Buy button to the Mac Pro web page.
The whole app is running on free/dev tiers on Heroku, so hopefully Apple releases the new Mac Pro before too many people sign up and I have to pay mailgun to send the email.
