Apple surprises everyone by announcing a new machine today: the eMac, an all-in-one computer that looks a lot like an old-style iMac, only with a 17-inch screen. It looks a lot less sexy than the new iMac, but also lots more rugged and, as the name suggests, it'll only be sold to education users. News.com carries details of that, plus a new PowerBook that sports higher screen resolution, improved processors and other goodies. All this represents a continuing move away from only announcing major upgrades and new products at the twice-yearly MacExpos, but is bound to set the gossips asking: just what is Steve Jobs going to announce at New York MacExpo in July?
