mrsellout: Right now, you need to manually enable Conky's rotation. My .conf file switches layouts depending on device orientation, so that you get a portrait mode-compatible layout when conky is rotated. However, I don't yet know how to enable rotation the moment conky is launched from a command I could run from within Conky.
At any rate, I'm glad you liked it. Also, you may be able to avoid the need to copy and paste the conf file's contents into a blank file if you download directly from the N900. I saved it, renamed it, and uploaded it, from the N900, and will probably continue doing so, so you may be able to avoid whatever openings/saving/renaming it in Windows causes.
