They are an impressive feat of technical prowess, no questions asked there. Whenever I look at the innards of an iPhone or a Galaxy I am not only impressed, but -- with all the wear and tear of the EE that's buried inside my soul -- I can only shrug and admit that the electronic design is way, way past my skills. That being said, the impressive design of the PCB and of some of the chips aside, smartphones are a failure of engineering. As mobile phones they have to do two things: - Move, and - Allow you to talk on the phone. Very much like a mobile seat, say, a car, or a wheelchair. If I were to build a car or a wheelchair that could only go for fifteen kilometers or so -- and generally move, but not at an impressive pace, would you be happy? I, for one, wouldn't, Battery technology is, indeed, the major setback, despite the incredible research activity that goes into it. However, I think they made the wrong trade-off, not only regarding to battery life, but also regarding software development and deployment options and especially user interaction. Choosing trade-offs is the root of engineering. > I guess we should all go back to our brick phones and blackberries for the business types then? I'm dead serious about it. Between my tablet and my brick phone, I can do everything that my colleagues who have smartphones can do. I also enjoy a) the benefit of a larger screen estate and b) the laughs when their portable devices are useless in the evening because they forgot their chargers at home. Bonus if I'm the one who has to call the cabs for everyone after a few rounds of drinks, because my phone is the only one still running.
