Like others have mentioned, the big benefit of owning the iPad is obviously the bigger screen. Although I find myself using my iPhone more than I do my iPad. Although I do use the iPad more for web browsing, reading, etc. I still tend to favor my iPhone for Twitter and Facebook though. Otherwise, I still use my iPhone for pretty much anything (including games). But since my MBP sits on my desk, I definitely pull out my iPad when I want to browse a web sit real quick. Especially since my iPad generally is right next to bed, so there is the convienence factor there too.
