Let's say the user starts with a 16GB, class 6 SD card. What are the benefits of storing apps to the SD card? Does it let the phone run smoother? Does it allow you to install more apps on your phone? What are the cons? Do apps take longer to open/load? Is there a risk of damaging the SD card and/or the phone? If someone could explain this to me as thoroughly as possible, I would greatly appreciate it. Thanks.
