You'd have to provide a (µ)SD-card, which might be a problem mechanically (the Pi2 has a much better card-slot, however). Time for boot-strapping, general latency and the need for a shutdown before switching it off might be another problems with Linux, so it has to be programmed on bare metal or something like RISC OS. It is a great desktop system with all the support it gets from the foundation and its users, but that's about it imo.

I have created highly reliably Kiosk systems with the Raspberry Pi, using techniques to make most of the file system READ ONLY. This prevents any shutdown problems. The Raspberry Pi does what it does very well, but as you said it is no substitute for dedicated bare-metal hardware solutions. I think most would agree that on a price/performance scale the Raspberry Pi ranks among the top contenders.
