Technically you may be right, just as technically it was illegal to record an album you owned on vinyl to cassette so you you could listen to it in the car back in the day. Or for a more modern take, it may not technically be legal to rip your DVD and Blu-Ray movies to a hard drive for use in your media center. The concept of fair use with regards to platform shifting is, and always has been, murky.Please be aware that "fair use" (as that term is defined by copyright law) does not apply to "acquiring" illegal PDFs, nor does owning a physical copy of the book make having a copy of an illegal PDF any less a copyright violation.
I'm all for the idea of having an electronic version of the 5E books myself, but let's not delude ourselves into thinking there's some kind of legal loophole or excuse that makes illegal PDF copies any less illegal.
