Excerpt from an extensive Walt Mossberg iPad review (no wsj.com subscription required)
My verdict is that, while it has compromises and drawbacks, the iPad can indeed replace a laptop for most data communication, content consumption and even limited content creation, a lot of the time. But it all depends on how you use your computer.
If you’re mainly a Web surfer, note-taker, social-networker and emailer, and a consumer of photos, videos, books, periodicals and music—this could be for you. If you need to create or edit giant spreadsheets or long documents, or you have elaborate systems for organizing email, or need to perform video chats, the iPad isn’t going to cut it as your go-to device.
