The Samsung Galaxy Tab S is good. Really good. With long battery life, a stunning screen and an especially thin and light design, it's a near-perfect product. Our main hang-up is that the performance doesn't always feel as brisk as it should (the forthcoming LTE edition uses a different chip, and has the potential to be faster, but it's unreasonable to ask someone to pay extra for the kind of performance they should have gotten on the WiFi-only models). In addition, the fingerprint scanner, though nice to have, can be temperamental -- so much so that we more than once locked ourselves out of the tablet. Finally, Samsung's Magazine UX feels a bit overbearing, mostly because you don't get the option of uninstalling it.
It doesn't look like that UI is going anywhere, but we do believe Samsung can address those minor performance issues via a software update. And even if it doesn't, this is still an excellent piece of kit. All told, we'd offer the same advice we would to prospective iPad buyers: Unless you want the extra screen real estate for watching movies, just buy the 8-inch version. It's cheaper, with a crisper screen, identical camera and just as much horsepower as the bigger model. Either way, you can't go wrong.
