However, Rose points out that the old TM may still be under warranty, if we could just find the documentation, so I don't unpack the new TM and take the very small risk of carrying on.
Last night my iMac goes down. I now have a choice between
*Getting the old machine repaired at a cost of about 50% of its value
*Getting the data off either the TM or the IM at considerable cost and buying a new Mac at a particularly bad time in the cycle
*Getting the data off either the TM or the IM and using one of the other three house computers while waiting for the new iMac release
