Tech Answers is back! Didja miss me? This time I've got something special for you. Now, I've sampled a veritable cavalcade of different smartphones over the years, from the Treo, to the Blackberry, to the iPhone, and, most lately, the Android. There I landed, and—for the foreseeable future—there I stay. The Treo is long dead (bye-bye!), Blackberry is a dead man walking (so sad), the iPhone's one-time supremacy in the smartphone market is faded (but not gone!), and Windows Phone? Please (no). Android is flourishing when other smartphone platforms are stagnating for one simple reason: it is free and open source. Developers and individuals can do whatever they please with it. You can go to the Android project's site and download the source code for the world's most powerful mobile OS right now for no charge. It is that openness and its benefits that I'm going to ramble about in this post.
