A number of third-party vendors are running out of the 15-inch MacBook Pro, AppleInsider notes. J&R is listing 2.2GHz systems as "out of stock," and 2.4GHz machines are "on order." Best Buy's online storefront has stopped doing home deliveries of 2.4GHz Pros, and while it is continuing to sell them at retail, many outlets in US cities like Austin and Chicago may not have units available. Another reseller, MacConnection, briefly ran out of 2.2GHz Pros earlier this week but now has units again.
