I've had my eye on this for the past week or so.
The problem is that it's only available for order online or via their "Ship to Store," and every location I've checked reports none in stock.
I wish I could say I trust Best Buy enough to believe they'd ship the i7 instead of the i5, but I don't. There's always the option to return the MBA if it isn't the Z0ME model, but I frankly don't want to spend the hours required.
