The main problem I have as a Chocolatey early adopter is that it still lacks an uninstall function, and once you have a respectable amount of packages installed through Chocolatey the update 'Chocolatey is going to determine all packages available for an update. You may not see output for a while...' can take upwards of 5 minutes, even when there's nothing to update. When Chocolatey updates a package it keeps both the old and the new version, my hope with the Windows version of it is that it includes this functionality. Basically I'm hoping the official Windows version will be a better, stronger and faster version of Chocolatey, that also improves on its base functionality. I am aware this won't mean much to the average user but it was enough to convince me to at least try it out over adamantly sticking with Windows 7.
