How are you using Time Machine? Over the network I've found it incredibly slow; and of course my network is more or less unusable during that time.
It is simple when it works. However, it is not very good at communicating its status and since I've had it fail in the past, I'm never quite sure its working when it takes long pauses in updating its status.
