It's 7:17AM and I just caught the express train from Princeton to New York City. This morning will be a little different, though. I won't be doing what I typically do during a trip into Manhattan like browsing the latest blog posts and articles about internet marketing, writing new blog posts or using Twitterberry to Tweet on Twitter. {Try and say that 5 times fast!} No, this morning I am going to test the limits of the mobile web. That's right, I'm going to buy something from my Blackberry! Yes, I know that's bold… You might be wondering if buying something on your mobile device is seamless yet? Not consistently. Is it something completed often? Definitely not. I'd actually argue that some people don't even know it's possible. In addition, many companies unfortunately haven't made the effort to ensure that your mobile buying experience is easy. This translates into a lack of user trust. And when you have a lack of user trust, people won't act (or in this case, buy). But there's an exception to every rule and that exception is Amazon.com when you are referring to mobile e-commerce. I was ridiculously impressed with my mobile purchase the other day. Let's explore why.
