FWIW, I've had a hassle at the xray machine because of my non-Apple MP3 player. That doesn't mean I'm going to make my own fuss about it and not bring it.
We should never be hurrying through security anyway, we should add in time just in case something looks funky in our bag. Heck, before the whole battery thing was mentioned in the TSA rules, I had a simple pack of batteries in an unopened box labeled batteries questioned. The bag was run through the scanner multiple times before they asked me if they could open it (after I'd said "it's batteries, it's on the end, please just open it" more than twice). That doesn't mean I don't bring batteries.
It's perfectly fine on the plane. If DH needs it, he needs it. You don't want it broken. I know I don't want a cellphone on in my room all night to run an app. Make sure you're not rushing, pack "politely" (not a bunch of stuff crammed all over other stuff), and carry it on. No biggie.
