If Leonard had a smartphone...
Would his life be completely different?
shareDepends when he got it. Most likely, he'd either forget it was his or drive himself crazy (crazier?) having to re-tattoo all his password resets.

I may find out someday
I'm absolutely obsessive about using my smartphone as an events-based journal. I have daily records going back to 1989, when I got my first Mac with HyperCard. My journal started including actual event times when I started using Palm devices. I've saved all that data as a Word doc with a password that only I know, and I update that Word doc weekly.
Someday, I'll wake up post-dementia, with that password hopefully still accessible (since earlier and more habitual memories seem to survive the longest).
At that point, I'll be Leonard-with-a-smart-phone.
But yeah, this film would be way simpler. He wouldn't need to reset his password, just make sure the phone's on him at all times so people like Teddy can't mess with it. Plus, instead of tattoos, he can record audio or video messages to himself, which would be that much harder to fake.
Y'know a use of a smart phone might make an interesting remake of this film.
Too unreliable, could get stolen or messed with. Tattoos are tamper proof (other than by himself)

shareThere were no smartphones. A PalmPilot was probably expensive but had email/calendar/notes.
