I'd be fine with it. Yes, it's true that the conditions under which "loss" occurs differ between hardware and software, but I would deem the difference to be below the level of GURPS' resolution. It rounds to a perk either way, so to speak.

If rationalization is needed, I'd simply speak from personal experience: It's just about always the configuration file(s) and never the software per se that's the issue. These tend to be lost not due to data glitches and such, but because a new software version renders them obsolete. If the GM intends to allow EB to apply to software, then it would be fairest to have software evolve such that using outdated stuff gives a de facto unfamiliarity penalty. At some point, then, tasks will be at -1 or worse if using the old stuff but still at +1 for the EB.
