By Lindsay Sakraida, dealnews Features Director While we're anxiously awaiting a supposed update to the Apple MacBook Pro series of notebooks, there are rumors that the hefty 17" model will eventually (whether now, or later) be phased out due to faltering sales. According to MacRumors, Apple sold 3.1 million notebooks in the first quarter of 2012, "with nearly half of them being the 13" MacBook Pro." But the 17" MacBook Pro has sold significantly less. In fact, an analyst quoted by MacRumors estimates that for every 30 13" MacBook Pros sold in that quarter, just one 17" model was sold. That would seemingly indicate that consumers are favoring lighter, more mobile machines. Often times when a product isn't selling well it will see comparatively steeper price cuts, so we looked back on our deal archives to see which size models in the current MacBook Pro lineup are seeing the better discounts. But the 17" MacBook Pro base model (currently $2,259 with free shipping, a low by $21) has seen deals that take 10% off the retail price while the base 13" MacBook Pro's price has been cut by as much as 12% (currently $1,119 with free shipping, a low by $1), edging out the larger laptop for a slightly better discount. Despite this, Apple has been trending toward lighter, portable products, exemplified best by the MacBook Air. And, there are many rumors that suggest the manufacturer will slim down the Pro line significantly as well. Whether there's room for a 17" laptop in that new design direction remains to be seen. Readers, how many of you use a 17" MacBook Pro? Are the smaller 13" and 15" sizes sufficient for your needs?
