The grass is always greener syndrome, and if we all lived by that with all be walking with the original cell bricks of the early years. NO matter what phone you buy within a week to ten days there will be a newer, better, faster one at its haunches. Stop sweating it, when you need to chane (albeit I said need to change not want to change) find the best at that moment buy it, and dont look back, otherwise you will die, if of nothing else, envy, or jealousy.
