I put the 128GB wifi (gold) in my cart. At checkout I decided I didn't really need the 128 and switched to the 64GB.
Then, I went to checkout again and changed my mind. . I've never regretted buying more than I really needed. It's buying less that can eventually lead to remorse. At least that's how I'm self-justifying the purchase of the 128GB.
I bought a case too. I went through my employer's website and saved a total of $22. Not much, but worth the xtra step.
Delivery estimate on the iPad is October 22-24. The cover is Oct. 21-23.
