Why does this supposed technological beast not pack Nvidia's latest Maxwell based mobile chips, especially at that price point? A single GTX 980m approaches the speed of TWO R9 M290x's in crossfire, and the GTX 970m follows in its bigger brother's footsteps, offering nearly as much performance, at a presumably much lower cost. Not to mention how laughable GCN's efficiency is when compared to Maxwell... This is just another underpowered Mac IMO. I laughed as my 13' 1200$ magnesium alloy/carbon fiber laptop had faster graphics (and twice the vram despite having much lower resolution) than the Retina Macbook Pro back in 2012 (and is still faster than the most recent model), while easily lasting more than 8 hours on a single charge (no thanks to Windows or it would be even better) with the sheet battery attached, and still managing to have a much smaller footprint and half the weight. I'll admit that the keyboard is better, and there is the screen of course but that cannot justify the price STILL. The fact that people continue to overpay for their things hurts me a little inside. If you are going to do serious enough work to require a 5k display, why pussy out on the footprint of your workstation? A mini tower could decimate this over-sized tablet all day every day. I realize there are no other 5k options available on the market today (probably because Apple pulled a fast one and bought up all the tech), but tomorrow (figuratively) Dell will release an Ultrasharp with the same panel and that will be that, though in the mean time a decent 4k monitor can be had for 500$.
