Extreme Laptop Abuse! Dell Latitude 12 Rugged Convertible Laptop Preview 

Thanks! I'm in the same boat as you for the most part, in terms of the size issue. For travel, I like a 13-inch machine but the AW 13 R3, for me would be a touch too bulky for my taste in that use case. For a machine around the house or office, the 13 would do great. On the XPS 15, I'm getting in their new Kaby Lake version in next, with GeForce 10 graphics on board. That thing should be sweet! It depends on what you do. If you're a hardcore gamer, the AW 13 R3 with GF 1060 will be more powerful than the XPS 15. If you're a casual gamer that wants a great looking, super premium machine, the new XPS 15 is likely going to rock big time. Stay tuned for that review, hopefully in a couple of weeks tops. :)
