Meter manufacturers need to start standardizing on Micro USB; it it the cable that is used with all cell phones (except for Apple), so almost everyone has the cable already. As you stated, computers no longer come with serial ports.
Let's face it; they want to sell strips. They should prove that they are forward thinking and not only modernize the data interface design, but offer the monitoring software for free.
Meanwhile, I'll build my own cable... I think I'll try one of those modules meant to interface to a oldstyle microcontroller. I just wish they came with shrouds for the USB end.
