It seems almost every technology analyst, reporter and blogger these days either believes that Apple is on the cusp of releasing an iPod touch-like tablet computer, or is willing to repeat the rumors to that effect. Some believe Apple will reveal a tablet in September, along with the likely announcement of an iPod and iTunes upgrade. Plus, Apple’s lean and mean next-generation of Mac OS X, a.k.a. “Snow Leopard,” is coming out, so September is a real possibility. Others look to give Apple more time — say, November — to get something out before the holiday buying season.
