Well, performance and memory usage are two separate things. Electron's performance is quite good and if your audience is "computer users at large", they won't care at all about the memory usage. I'd say you should almost definitely use it if you want to target Mac + Windows + Linux. Just know that you'll get wrecked on HN ;-)

I'm quite sure that you got that backwards. Your dev machine may run Electron apps fine with 16GB RAM, but a huge majority of average folks are on 4GB and often less. And they're already running Windows 10 (or at best OS X) and a web browser with a bunch of open tabs!
