I am considering purchasing a new iMac. I bought a Mac OS 9.1 system just before they uprated it so would welcome advice as to whether I should wait. Peter King
Whatever computer you buy, there is always a new model on the way. Apple usually updates products twice a year, but the next significant change will probably be the release of Mac OS X 10.5 (Leopard) around the same time as Windows Vista. Whether it's worth waiting for is up to you. However, you face a very big jump to an Intel chip that is incompatible with the PowerPC processor in your current Mac, and to an operating system where support for Mac OS 9 (Classic) is a low priority. A secondhand PowerPC-based iMac would offer a transition strategy, and preserve more of what you have now. But in terms of future proofing, the best strategy would be to dump OS 9 and take the great leap forward.
