I'm still incredibly happy with mine. It is the perfect size for what I am looking for in a phone and runs plenty fast for me. I still get enough battery life as well and it runs fast and crisp. I don't feel the need to upgrade at all. I am interested in seeing what HTC releases with the M10 and would consider upgrading to it sometime next summer if I like what I see. However, I feel no pressure or obligation to make any jump. If my phone were to die today, I'd probably try to buy a used M7 for cheap instead of making an upgrade to a 2014 or 2015 phone.
