Actually, there is ONE problem. The one-click install is setup to auto upgrade as well, which can cause problems with plugins that are not yet updated to handle the newest version of wordpress.
I noticed today that my two site’s auto-initiated the upgrade process without any warning. Yikes!

Thankfully though, this can be turned off - or set to notify first. To do so, which I would recommend, go to your Admin area > One-Click Installs > Manage Installed Applications and you’ll see the option to change the “Upgrade Action”.
