First, a point of methodology. The fact that the name of the site is “Software Recommendations” has no bearing on this question. The name is a historical accident, and the early beta is when we should validate whether that name and our draft of the scope is really what we want. Validation can be logical or empirical. We can experiment with hardware questions, and see whether they work. Or we can reason (based on data gathered elsewhere, for example on older Stack Exchange sites) to deduce whether hardware recommendations fit here.
Taking the logical approach, do hardware and software target the same audience? Yes. The audience is computer users of all kinds (including specialized users such as developers and administrators). We use computers as a whole. Our focus is on using finding the right computer-based tool to accomplish a task. Our toolbox consists of software running on hardware; in this light we can ask about the hardware parts just like we can ask about the software parts.
Furthermore some questions about larger systems will involve a combination of hardware and software, eg. “What architecture for a datacenter that offers this and that service with these administrative requirements etc.?”
Now, does hardware have specific problems that might make it unsuitable? This is where I'm unsure. There are a few characteristics that arise far more often when it comes to hardware than when it comes to software.
- Most hardware obsoletes more quickly than software. I'm still using many of the same programs than 10 years ago (newer versions, but that doesn't imply new choices); I have very little computer hardware that is that old.
- For hardware, price is a lot more sensitive than for software. For starters, there's a lot of free (as in $0) software out there. Then $300 vs $200 is typically not very important for software but is often a deciding factor for hardware.
I don't feel that I have enough information to conclude at this stage.
Taking the empirical approach, here's one: https://softwarerecs.stackexchange.com/questions/688/tablet-with-a-keyboard. I would like to see a few other (good!) hardware recommendation questions, so we have something to judge.
