I can honestly say that I have never been inconvenienced even slightly by an application that takes up between 0 and 500mb on disk.

If it starts to get into the multi-GB range it can hurt to download, but below that it's all identical to me. If it means that i don't need to run a specific version of a library installed globally on my machine, and i don't need to manage a big chain of dependencies myself, and it runs on multiple platforms, i don't care if it's 1mb or 500mb, and i don't care how many copies of it I'm running.

My ssd has 60gb remaining on it after a few years of daily use and i haven't needed to worry about program space yet.
