WSJ.com - Personal Technology: Handspring's Treo Now Offers Push E-Mail Like BlackBerry "...heavy e-mail users may want to wait to buy a Treo until this summer, when Sprint's version will come out. It will work on Sprint's forthcoming high-speed network, providing a nearly always-on experience for downloading e-mail, much like the BlackBerry does, eliminating the need to constantly place calls to get e-mail. It will also download mail much faster than the current Treo and will offer billing plans oriented toward heavy data use, thus limiting runaway phone bills. ... The bottom line, however, is that the Treo now has a new capability: automatic reception of e-mail. That means it can replace a separate phone and PDA -- and a BlackBerry as well."
