I don't see anything wrong with sticking with something that works for you. Just don't get the impression that anyone else should necessary accommodate your thrift. Software is deliberately made to be updated (otherwise it would be circuitry) and we're still in the first century of computer technology, meaning that no one is going to be able to afford to provide substantial software products that will work on all of today's myriad platforms, as well as every previous version of every current and previous platform. My company is very concerned about not alienating customers, but our product's next version will be limited to customers willing to upgrade to IE11 (and there is no IE11 for XP) and the latest versions of Chrome, Firefox and Opera. That already represents enough cost, for each release, such that we don't make profit on maintenance contracts. And every year services you may want to use will revisit their minimum requirements. For example, right now, TD Ameritrade requires IE8 or later if you're going to use IE. That'll change to IE9 over the next year or two, rest assured (and there is no IE9 for XP, either). Kinderhook Bank (for example) already requires IE9 (and therefore excludes folks running XP).
