Unless you either don't go on vacation or you take your computer with you, I'd say you wouldn't see a need.
I have kids who use a smartphone for just about everything. My home uses several different OS, along with several handheld devices. I try and stay up with the times and do some of the repairs.
So when my kids as a question pertaining such things as apps, software, OS systems, I don't have look on my face.
I access the Forum on my Kindle, and I downloaded the SCSW3 to the Kindle. I prefer to use at least a laptop though. I don't see the little screens too well.
I'm using tapatalk right now from my phone. I'm sitting here on duty with the reserves, and I'll tell you, this stupid app gets me in more trouble than anything else! It's so easy to just log on and get connected to everything. I've got about 5 forums on here that I frequent, and it will be the death of me.
