Also, what system is it running? For me, one of the main advantages of owning a mac is the OS - nice, slick, fast, *NIX (hence good for developers), without all the configuration hassle of Linux.
And you didn't say why you suppose more developers use Linux than OS X. My experience is the exact opposite.
They may need a particular flavor of Linux to test on, but those are typically server builds anyway, so not great for everyday computing. That's what solutions like Vagrant or cheap cloud servers are for.
If they offered the same memory and storage options, it would be a lot more attractive.
Also, trackpad still sucks compared to Apple's.
And the price really should be lower given that you get less value out of the box.
EDIT: Yes, I am referring to the Pixel here.
