Hi Jeannie,
Funnily enough at virtually the same time a user has posted in the Search the Internet plugin thread an example of one "issue" that putting series information into the title caused them.
I know nothing about your device, but it does make it a problem if you ever have a need for just the "raw" title again (which things like metadata searches, plugins etc can all make use of).
You are absolutely correct in terms of Calibre allowing you to do it and if you are happy with it go for it. But I would agree with theducks that it isn't an approach that I personally would recommend
unless you are fully aware of all the downstream issues of that choice
