Until I saw this graphic I thought the compact, point and shoot, camera was doing just fine.
Right. Of course. My iPhone 3G isn't good enough to replace a point and shoot, but my June 2010 iPhone will. I haven't been paying attention.
That's tech churn. From nowhere to everywhere to nowhere in no time at all. Reminds me of books on CD.
So is Amit Gupta right that the iPad has made the laptop obsolete? I don't think so. A good laptop is much closer to a desktop than a Point & Shoot camera is to a DSLR; there's room for both in the "pro and enthusiast" market. I do agree that specialty OSs such as ChromeOS and iPhoneOS will dominate the "everyday use" end of the market. The form factor is, however, less critical than the usability, security, business model and low operating costs of these next generation environments.
Remember too that, when the market demands it, an iPhone will support a keyboard and external monitor. Then you have a phone and a laptop ...
