If people see the iPad mainly as an extra device to carry around, it will likely have limited appeal. If, however, they see it as a way to replace heavier, bulkier computers much of the time—for Web surfing, email, social-networking, video- and photo-viewing, gaming, music and even some light content creation—it could be a game changer the way Apple's iPhone has been.
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.
Those comments come from Walt Mossberg in the Wall Street Journal.
Here is my own summary of the iPad's pros and cons.
negatives:
no physical keyboard, no Webcam, no USB ports, no multitasking, expensive, won't play flash videos, heavier than the Kindle, will need two hands to read, can't enter notes on books, fewer books available than on Kindle, no mouse, difficult to type on when upright, only can use one app at a time, no DVD drive.
positives:
touch-screen, excellent e-book reader, runs iPhone apps, thin, great battery life, very fast processor, calendar and contacts apps will sinc with Google and Apple, strong image resolution, magazines are being designed for use on it, TV networks are adopting their shows for play in the device, rotation-lock switch (to prevent switching angles).
