I had a case for my Nexus 10, but I found out it added extra heft and just got in the way 99% of the time so I got rid of it.
I have a leather and matte case for my white Nexus 5, but only because it needed the extra grip.
I've had smart phones for years now and I've never dropped and broken one yet. Cases aren't necessary for me.
I know you have never dropped and broken one yet but a case would definitely be a great thing to have just in case something freaky happens and you end up dropping your phone. I'm just sayin'. I've had smartphones since February 1, 2007 and I've always had cases on my phones, The way that I look at it, with how much money I pay for the phone, the case and screen protector is just a little added peace of mind for me.
Just putting my two cents worth in here. Take it for what it's worth.
Always naked...personally I think if the designers have spent all that time designing the phone that way, then that's how I should appreciate it's looks. I understand people want to protect their phones from damage, each to their own and all that, but for me ?...nah. I like the way my Moto G looks...I don't want to cover it up.
However, I find the G rather on the slippery side in my hand which made me rather nervous using it outdoors
Which back have you got Sizzers ?...I've got the original black one and it's not slippery at all to me, maybe we just hold them differently ?
