I don't know why you are being downvoted. I used to use Notepad years ago as it's practically guaranteed to exist on every Windows machine. I can't say much about productivity, but performance was abysmal for larger files. As for reliability, the main reason I never use Notepad now, even for most trivial things, is that Notepad++ will always bring my session back, with all open tabs, regardless of whether I saved the file or not. It doesn't matter if my battery died or Windows decided it's now time to restart the system after updating - Notepad++ will keep my work safe and Notepad will not. So speaking about reliability is probably a bigger joke than productivity.

They could say "We always wanted to keep the tool light, fast to start and reasonably efficient for small files, and we have managed to do that" - and this would be OK. There is no need to serve bullshit to a technical community.
