Touch screens are great until you need to use them while eating something greasy or messy. Now you have gunk all over your screen. Smudges, smears, and crap that makes it hard to see your screen.

I actually like the voice control when I don't get the dreaded "Voice commands not available" error. Luckily I have an iPhone with Siri. I can use voice commands with bluetooth audio and I never have a problem.

 

Common sense dictates that you don't touch the screen with dirty messy fingers, lol! I use voice commands sometimes, especially in those situations. Voice commands are great but usually take longer than just using the screen and touching the buttons. I was using my phone in light rain once and a few drops got on my screen and I swyped through one and it wigged out, screen moving and jumping randomly all over, lol!
