Every program you have to keep open all of the time because it takes a lot of time to startup and you cannot easily predict how frequently you'll need to make use of it, is more stuffed that ends up paged to disk until the latency caused by swapping makes it profitable to just start over again. If people have two choices available to them and one of them is apparently less annoying to them than the other, they'll typically pick the less annoying one. This is why so many 'average' people despise PDF files; Adobe Acrobat with its plugins and startup time makes casually loading documents annoying for them. Recalling how inconvenient and annoying computers were in previous decades as a means of excusing performance now isn't going to sooth users.
