A desktop tag showed up today, in this question. I don't think it contributes much (if at all). The linux tag, also on the question, tells us what we need to know. Anything that works on a linux desktop will work on a linux laptop. The possible exception that it might not be suitable for a linux tablet (because touch screen accessibility), but that should be indicated with a touch screen tag
That I think the desktop tag is bad, and warrants paying attention to. I'm not saying black list it now, but we should be aware of what it is doing.
