Anthony West and Data Racing have released a new mobile app for track day telemetry.

More and more, IT technology is becoming cheaper, more pervasive, and more powerful.

My keen interest as a programmer is how more and more technology segments are becoming 'commoditised' over time.  Previous specialist technology solutions that were once incredibly expensive are becoming cheaper and more accessible.  Desktop computers are so cheap now that they are throw away, the cost to replace is usually cheaper than the cost to repair.

Update: It is not obvious on website how you get the app.  The site seems to suggest this is still a work in progress and not ready yet.  Still a cool tech idea, if it is indeed a real piece of software under development and near completion, and not just vapourware.
