I too received my P3 from Dell about a week ago. I too saw it was out of stock and thought, "I'll try to order it anyway...see what happens." I ordered a 16GB black version and it shipped a few weeks after I ordered it. On a whim I called customer service during that period of a 2-3 weeks just to get an update. She said the would ship one out as soon as they would get it (June 26th or so). She ended up expediting my order and I got it a few days early. Great experience!
I too took advantage of (what I assume was) the Father's Day sale and got mine for $157 plus free shipping with my corporate discount. Not too shabby!
