The Tab is a rectangular slate about two inches shorter and three inches narrower than the i Pad. It is also a tad thinner. It weighs less than a pound, compared with 1.5 pounds for the i Pad. While its screen is smaller, it has almost the same resolution as the i Pad, so almost as much material can be displayed on it. The Tab has a 3-megapixel rear camera with flash and a 1.3-megapixel front camera mainly for video calls. Still-photographs and videos I took were of average quality, but videos taken with the front camera were fuzzy. The Tab uses the latest version of Android, and it generally worked very smoothly, even though Google has warned that Android isn’t yet ready for tablets. I was especially impressed with Samsung’s attractive and usable rewrites of the calendar, email and contacts apps, which, like their i Pad cousins, use multiple panels to make them more computer-like, while still remaining touch-friendly.
