I don't see it that way at all.

IMHO, having a Linux OS is a great plus for embedded systems. This makes creating, maintaining and enhancing the user software much more comfortable and a developer can have a pool of easily reusable software snippets he can use in all his projects. Of course the support for multiple languages is a big plus, too. Moreover with the upcoming "!internet of things", support of standard software on embedded devices becomes more and more essential. The user want to control their appliances with a smartphone (or a PC) but directly attaching a monitor is not a decent option.

In the rather near past, hardware cost was a limiting factor for the use of Linux in small embedded devices. But as we see, this problem is vanishing. I recon, very soon we will see ARM chips with enough integrated RAM to run Linux (doing away with the hard-to-do "RAM soldered on top" technology the RPi uses). With that, doing a Linux enabled PCB will become easy for small shops (like ours).
