I'm tempted, but I'm also OCD when it comes to my devices, so I keep it in a case. Also a major consideration is the resale value of a mint or near mint device.
Naked until my first iPad slid off the bed and hit the floor.
Nothing happed but I got religion.
Bought a Chinese leather case with a magnetic clasp.
The clasp put a dent in the back shell of the iPad
Handful of clips and a new shell and we were back on the road again.
Ever since every iPad has been in a Scosche foldIO case
Has kept the front and back protected and looking like new.
Totally naked for all my devices. iPad, iPhone, MBP. I feel Applewent to the trouble to make it thin and feel right in the hand, so that's how I keep it. I just take care of them. No scratches on any of them.
