Using an expensive Apple notebook as a development platform is a poor choice when compared to buying a Mac Mini with a third party keyboard, mouse, and display. Maybe two displays for seeing more source code at the same time.
A colleague from our corporate offices visited here with just this setup. (His predecessor had a 2005 17-inch PowerPC laptop and he wanted to replace the hard drive with flash in 2010. So he agreed to put the computer on a SEVEN YEAR depreciation -- from 2010! -- to get his flash. Then got himself fired a few months later -- this was not the only example of the guy's obnoxiously arrogant incompetence -- leaving his successor with an ancient creaky laptop that can't be replaced until 2017.) He put his backpack on the desk, pulled out the mini which was wrapped in a thick towel, and asked for a keyboard, mouse and monitor. We all agreed that this was about the most pathetic dorkiest thing we've ever seen outside of a windoze shop...
What laptop, exactly, are you talking about? Because it seems like you are either A) confused or B) know very little about the laptop market.
In 2012, there was a 15-inch MBP without retina line and a 15-inch with retina line, with low-performance, mid-performance, and high-performance options on each line. So I could get the highest performance
computer (8GB ram, 1TB disk, 2.7 gHZ quad-core i7 Ivy Bridge) with
out a retina for about the same price as a mid-performance computer
with the retina. Sure, I'm happy to take a retina
if it's free, but it's far from free. In 2012 the latest and greatest top-of-the-line computer underneath a retina display was $3,400, while the latest-and-greatest without the retina was $2,600. The non-upgradability is a huge issue for me, too -- every MBP that I've bought (starting with the original in 2006) I have doubled the memory within the first year for about $100, while buying it initially with that amount of memory would have cost $500-$700 more.
I don't blame Apple for abandoning the product, because they didn't sell that many of the non-retinas. (MacMall liquidated the 2.7 gHz i7 Ivy Bridge MBPs for $2,000 last year.) What I blame them for is losing all of the geek customers...
Edited to add:
I also am intimately familiar with apple laptops, having bought my first one in 1995... With the 2012 product line, I bought six 13-inch MBAs for reporters and three 13-inch MBPs for photographers. They were the same price. The reason that we went with the MBPs for the photographers is that they consume huge amounts of disk space and we couldn't afford the storage they needed in an MBA. A year later when it came time to buy four laptops for sports reporters there was absolutely no question that we were going for the MBPs. Now matter how much I scold them and threaten beatings, our reporters abuse the MBAs in terrifying ways. I keep waiting for one of them to stick a finger through a screen in the middle of a rant. And it's a wonder that they can see their displays at all, with the coating of grime that they put on them in just a few days.
So it isn't just the programmer market that is being abandoned. If Apple doesn't come up with laptops with adequate specs that we can afford, then we are well and truly screwed.
