Query: Disappointing ... Wait ...

As a new Mac convert (1 year on a MacBook) I was actually eagerly looking forward to Leopard largely for Time Machine - to easily and simply manage backups for our family's 4 Macs.Sadly, Apple stripped out the most important network backup functionality from Time Machine just before retail release and further ... I (and frankly many others) have found curious disk compatibility issues with Leopard and Time Machine that are reproducible and worrisome. I have several USB disks that I attempted to use with Time Machine (even after extensive reading of Apple's support forums) that are corrupted and unusable after the attempt to use with Time Machine.I remain unsuccessful in getting Time Machine to reliably work.The other features of Leopard are nice, but few are really compelling other than Time Machine.I would wait as Apple should have done .. until this product is really ready for end users.
