15-Inch MacBook Pro's Becoming Hard To Find , Could Suggest Product Refresh Soon –
Apple Insider noted today that third-party resellers are struggling to keep Apple’s 15″; Macbook Pros in stock. This is normally the cases when the product inventory is low and suggests that we are a few weeks away from seeing a refresh to this product line. We seen this happen weeks before the 3rd Gen Apple TV was announced.
Among those resellers reflecting backorder status on some of the current 15-inch MacBook Pros is J&R, which is now sold out of both the 2.2GHz model, which is listed as “out of stock,” and the 2.4GHz variety, which is currently advertised as “on order.”
In addition, Best Buy has also stopped accepting online orders for the 2.4GHz model for home delivery. The 15-inch notebook is still available on a store-by-store basis, however a quick check of individual store inventory in cities such as Chicago and Austin similarly indicate that between 40 and 60 percent of those shops are similarly reflecting stock outs.
