It needs user adjustable parameters for frequency of backup, bootable disc mode, file/directory settings etc that are commonly available on other off-the-shelf backup products. I still use Carbon Copy and .mac Backup and can't see any benefit to Time Machine whatsoever.

Maybe future updates will make it a little more user-friendly.
