I'd go for a computer over any smartphone setup. Main reason is for rain as most of these devices are water resistant. And you'd have to buy the iphone mount, and probably a good case just in case it falls off. And there's always the battery. I bought a $20 Walmart one and after 4-5 months of almost daily riding, I never had to change the battery and it worked great. Only had to replace it because the bike was falling and out of instinct I grabbed the first thing I could, which was the computer's cable which then broke.
