I'm running it on 2 GB RAM (Acer C720 Chromebook, 1.4 Ghz Dual Core CPU) and it even works really well here, much better than the other Linux distributions I tested, feels like a whole new computer. 2 GB is really not enough nowadays but with elementary you can get away with it for a while longer :)

Just one caveat right now, there is a bug with Intel graphic chips where videos freeze and only play audio unless you move the mouse cursor around. There's a workaround but it disables hardware acceleration so it'll use a lot more CPU, so if your laptop has an Intel chip you might want to hold off for another week or so until the bug gets fixed.

I just fixed the last few issues so I should be ready to submit my app in the App Center later today :) The elementary devs will probably not work over the weekend to review my app, but it should hit the App Center some time next week. Installing directly from source is really easy too though as I explain in the readme file, and you can uninstall it again with sudo ninja uninstallso you don't need to worry about it leaving any files behind once you move over to the App Center version.
