My gadgets seem to have formed a kind of energy conspiracy: I’m at the “Mensch und Computer” conference in Gelsenkirchen, Germany, and not only does my indisposable indispensable PowerBook’s battery not last no more than 75 minutes (if I’m lucky). I brought three sets of rechargable batteries for my digital camera, I even tested them at home ? and now all six of them are flat. I haven’t been able to take a single photograph with the camera and had to use my mobile phone’s low-res camera instead. I’m happy though that my Treo’s battery still agrees to work quite nicely, and my iPod’s ok too. (I keep my fingers crossed ? got a longish train travel home tomorrow.) I hope some future developments will help us get rid of nuisances like empty batteries ?
