Am I the only one to find most mobile websites worthless? They try to be too clever and hide too much stuff. Or worse they only expose a small piece of functionality. I rented a car once and needed to look my reservation up on my phone at the counter. The mobile website would only let me book a new reservation and had no link to the desktop version. Yeah the article recommends apps over the websites. But now I have to spend time downloading something that also may have worse functionality.
