If you hesitated even a moment when ordering the new Oasis, chances are you are on the waiting list and won't get your device for days or weeks.
While you could wait for Amazon to catch up with the backlog, there is another option. I heard via MobileRead that Best Buy has the Kindle in stock. You can walk in today, buy one, and take it home.
I just checked my local stores, and they all have the new Oasis in stock. Supplies are running low, though, so if you want one you need to act fast.
