That said, I bought Lightroom 3, and when Lightroom 4 came out, there weren't enough improvements for me to justify the upgrade price. After that I never got round to upgrading, so I'm still using Lightroom 3. And it's still just fine. I use it pretty often, but no where close to 10 dollars a month.

I met a CS student who was still not sure he should upgrade from Windows 7 to 10 and it's free! All because of "it will have Metro". Can't be bothered convincing idiots.
Also, to settle the Arduino/Raspberry Pi thing, Scott is 100% correct. The RPi makes Arduinos completely unnecessary, as the RPi does have a header with plenty of analog and digital I/O pins. RPi is just overkill for most Arduino applications. You'd need to wire up whatever I/O pins to some small relay driver circuit.
