I scored one of these yesterday. It was quite a bit of effort, but well worth it!
I found out about it quite early through SlickDeals since I had an alert set up for 'x4300h'. Despite that, my local Frys in Renton was already sold out. I couldn't believe it, but I suppose that's what happens when you live in an area with a high concentration of techies. I then checked the next closest Frys, which is in Wilsonville, OR - a 3.5 hour drive away on a good day. They showed availability, so I ordered it online with in-store pickup at the retail price of $1499.
The next morning (Saturday) I got the confirmation that the unit had been reserved for me! The sale didn't start until Sunday, but I had until Monday to pick it up.
Fortunately the intel from SlickDeals was spot-on, and I received my promo code email early Sunday morning. Not wanting to make such a long drive in vain, I called Frys shortly after they opened to make absolutely sure the unit was set aside for me. As it turns out, it's a very good thing I did. After being put on hold three times, I finally got through to the supervisor on duty and she said that no unit had been put aside for me(!), but there was still one left in stock. She had one of her checkout people literally run to the audio area and bring it back to the holding area in checkout. Once that was done and she assured me that it would be here, I thanked her profusely and got on my way.
10 hours and 430 miles later (cursed Portland and Olympia traffic) I stumbled back through my front door, prize in hand! I was too tired to set it up, but I'm really looking forward to doing that tonight!
