Samsung quietly introduced the Galaxy Tab4 line on Tuesday in three of Samsung's major tablet sizes, 7, 8 and 10.1 inches. The various dual-core CPUs from the Galaxy Tab 3 series have been dumped in favor of new 1.2 GHz quad-core processors and the tablets now get 1.5GB of RAM instead of just 1GB. It's a modest step up, but even that's more noticeable than the screen change: The new models all have a 1,366x768 resolution display, as opposed to the predecessor's 1280x800 resolution. The best update may be stylistic, a move away from a slick plastic back to a matte, textured one. Each device--available in both black and white--will run on Android 4.4 KitKat, and have a relatively weak built-in 3MP rear camera and 1.3MP front camera. The Galaxy Tab4 7.0 will be sold with 8GB or 16GB of storage, while the Tab4 8.0 and 10.1 will be offered with 16GB of storage. Each model has a MicroSD card slot for those who need extra space to store apps, video, photos and documents. What they don't say in the press release: Clearly, Samsung is going for a budget play here. When the company says it's an 'exceptional multimedia experience for the whole family,' it means that you may not buy these for yourself but you could buy it for your kids. The Tab 3 series sells for just over half what its Apple-based competitors sell for, and the 2014 specs appear to be basically just tweaks based on the cheapest available components. These devices seem competent for presenting video, books and games, but just be aware that they're not premium products. Samsung does say that the three tablets will all ship sometime in May or June.
