I've just spoken with Amazon phone support regarding my August 1 delivery estimate for the 1.83 MacBook I ordered on May 29. I was told that Amazon has the MacBook release date listed as June 15 (which is weird considering the rumors of people claiming shipment confirmation emails...), and that orders should ship within 24 hours of their release date (again June 15). Oh...I was also told that I would receive processing priority due to my selection of 2-day shipping. Apparently selecting the free shipping option drops your place in the cue. So if you've chosen the free shipping option, you might want to upgrade in order to keep from chewing your arm off in frustration at having waited weeks for your order, only to have to wait longer for Amazon to restock their initial MB inventory.
