Welcome to another issue of Total Amiga which, as usual, is packed with items from a wide range of contributors. This issue we finally have some concrete news on OS 4 to report with the release to early-bird customers of the Developer PreRelease on CD. These long-awaited discs let AmigaOne owners finally use their machines with the OS for which they were built and try out some of the features we’ve been talking about in our OS 4 features for the last few issues. Whether you're an AmigaOne owner and have your CD or haven't yet taken the plunge we hope you'll find our special edition of OS 4 Update interesting. For AmigaOne owners we have included details of how to update your flash-ROM as required to run OS 4 and some tips on how to get the most from the pre-release. For others we cover some of the new features that have been included on the pre-release CD. OS 4 development did not stop with the pre-release so we also look at some of the features still under development that will be included in the final version. On the other side of the pond that is the Amiga community, we have a review of Genesi’s latest hardware release, the Pegasos II PPC motherboard with G4 1GHz CPU card. Paul Rezendes reviews the board for us, approaching it as a new user coming from a “classic” Amiga background. Sometimes it’s good to hear a different point of view, so I was interested to receive an article from new contributor Mark Smith stating his strong opinions on the Amiga marketplace. It certainly gives some food for thought for companies and organisations that would see Amigas and Amiga-compatibles as successful products in the wider market. As usual if you have any comments on anything published in the magazine then please send them in, I will include a selection of responses in a letters section.
