On balance, however, I still prefer the iPad. For one thing, I like getting twice the screen size for a little more money up front—as little as $29 for the no-contract model with cellular capability. For another, the iPad has vastly more apps specifically designed for a tablet versus a smartphone—about 40,000 according to Apple, compared with just a handful for the Tab. And it can run about triple the apps overall, if you count smartphone apps that aren’t optimized for tablets.

Also, in my tests, the iPad’s battery life was about five hours better than the Tab’s, its maximum storage capacity is higher, and its aluminum body is more rugged than the Tab’s plastic casing. Finally, the iPad can be bought in a Wi-Fi-only model that frees you from any entanglement with cellphone carriers. The Tab also has Wi-Fi, but, so far, no Wi-Fi-only version, though Samsung is promising one next year.
