When will Shopify get Sqaure quality card readers?

At a vendor market this weekend, I noticed TONS of vendors with the Square iPad card reader.

This thing is $150 and it literally fits around an iPad and has a built in card reader.

WHY is Shopify so backwards and behind with this? They made that super expensive POS on the Go device that only works with Wi-Fi and a very limited supply of card reader options.

The retail kit is $219 and the card reader is a separate device from the iPad mount. I mean Square even has a card reader that prints receipts!
