There are a lot of hybrid tablets coming out this year. But while the ones we've seen seem to be splitting the difference, Dell seems to be focusing on the best parts of either laptop or tablet. Its XPS 10 is the tablet end of that bargain.
The XPS 10 is a 10-inch ARM-based tablet that comes with a keyboard dock. That's a decidedly different pill than, say, Samsung's Ativ Series 5 and Series 7 slates, which feature their keyboards much more prominently. That is to say, the XPS 10 is designed to work as just a tablet.
That seems like a small distinction, but it's an important one. While Samsung's machines are mainly built as laptops (they run the "full" x86 version of Windows 8), the XPS 10 is an ARM-powered device, so it's thinner, lighter, and more like a tablet you'd buy for actually using a tablet.
The keyboard on the dock, which also doubles battery life, is a little undersized, but going through speed tests on it, it wasn't small enough to lose very much comfort or any accuracy, so it doesn't seem like a huge deal.
