I found this program and it turned out to be not just useful but also light and very easy on resources. Another thing that I also really like (or want) is good looks (the reson why i'm still not on Linux, I know I suck) which this little app definitely got the edge in.
It has costomizable skins and a lot of plugins. One of the plugins that comes prebuilt is the Outlook Plugin. So useful if you have a Windows Mobile PDA because the only thing the calendar can sync is Outlook (Todo list can olso be taken from there).
Anyway, enough talking just get and see for yourself.
