I’ve taken to browsing the Web with a mobile device like a duck to water, despite the generally appalling user experience. I remember well the days of balancing hot and heavy Dell laptops on my middle, recumbent on a sofa — peering awkwardly at an obscurely angled keyboard, lap getting hotter and hotter. Relief came when the Nokia 770 Internet Tablet debuted in the U.S. in November 2005. I thought the 4.1-inch screen Debian-modified Maemo OS device was a miracle — and it kind of was. You could hold it in one hand and poke away with the stylus with the other.
