I probably have written this three times (at least) by now, but I'll repeat myself again. The current G5s are terrific - I love mine - but in June they will be a whole year old. It really is hard to believe, but it is true. They line could be updated at any time, but at the latest, new ("Rev. C") G5s will be seen at the Worldwide Developer Conference in late June. Many expect the upgrades to be significant. Since we're on the verge of that announcement, unless you really want one now, it will definitely pay off to wait.
