Wireless: After nine days of doing little other than living, breathing and dissecting an iPhone, Tom Yager calls it “a really sweet mobile device.” But, putting consumers and gadget freaks aside, for business users it’s little more than a $1975 iPod. Problems include price, the monthly payments, it’s overstated quality as a phone and mobile browser, the fact that it’s closed to third-party development. “I can’t recommend it. The unhappy fact is that for all the glamorous marketing and positioning, iPhone turns out to be the worst $1975 investment (iPhone plus two years minimum, mandatory service) you could make in mobile communications.” Related: iPhone spurs developer renaissance and Analyst predicts iPhone based on iPod nano. Notes from the field: Robert X. Cringely makes the bold move of putting Windows Vista up for adoption. Why? Well, two reasons. First, nearly six months after launching the OS Microsoft still feels “compelled to issue talking points that OEMs could use to convince customers not to wait for SP1.” Second, Cringe writes, “corporate customers have been clamoring for easier ways to downgrade from Vista to XP so loudly that Microsoft actually … simplified the process.” What’s more, a reader makes a pair of arguments the sum of which is that “Vista is at least 18 months away.” The news beat: Microsoft CEO Steve Ballmer talks up software-plus-services, sharing more details about the company’s plan to make such a transition.
