I have not tried TM Manager, but wanted to give a warning to those that enable TM for use over a network.

First off, here's how to turn a networked disk on using the Terminal:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Now that you know how, go read this post from someone who lost some data / backup while using TM. Makes me want to go out an buy an external hard drive and not use my NAS.

Thought you might want the heads up.

This app was not on my radar for the promo, but wanted to give it a fair shake. I have to say, it smells like a Windows port, in a Mac Microsoft Office '98 sort of way.

As others have stated, this is a non-standard application that isn't logical to use. There is little that is Mac-like.

I will say that the drill-down feature was nice and worked well. The templates and eye-candy weren't too bad either.

One feature that is missing, and a deal breaker for me, is export to HTML. I tend to use a mind map program to lay out my clients Web sites and site maps. If XMIND cannot handle this very basic function, it is of little use to me.

I'll stick to the free OpenSource program, FreeMind.
