The Mac community has been busily working out what "the end of summer" means in Applespeak. For this is when the Mac maker had promised the eagerly anticipated 10.2 version of OSX, an upgrade that should deliver a bunch of goodies including improved display on LCD displays, better performance, an integrated instant messaging program, and other stuff. Most had taken it to be sometime in September, even October (this is, after all, a software release, and these are always subject to slippage). But now CNET News.com suggests we're looking at August, to catch the "back to school" market, in a possible attempt to kick-start a slow year. The announcement - whatever the timing - will likely be made in just under two weeks, during Steve Jobs' keynote at MacExpo New York.
