None.

Atom's installer is a huge download, and the editor is much slower ... It also consumes much more memory and written in coffeescript. Takes a long time to start up ... just a few things on the top of my head.

It's a great initiative though so that's already a good point.

I just timed it and it was less than 5 seconds. I would suggest giving 1.0 a spin before you judge.

Thats still a long time for a text editor though. Sublime, Vim, gedit, etc are all instantaneous.

On this MacBook Pro (MacBookPro12,1) i7(3,1GHz) 16GB of RAM, 512GB SSD ... it takes less that 5 seconds which is way to long for me. If that's ok for you no worries, but you can't say it isn't slow.

My Emacs with all customizations takes longer than Atom does to startup.

Which, for Emacs, is not an issue at all. Leave the server running and all clients will open instantly whenever I ask.
