I've seen quite a bit of discussion on this and I thought I'd just weigh in. External GPUs have been attempted - but nothing like the Razer Core. We worked with Intel, AMD and nVidia to make this happen and it's truly the world's first true plug and play external gaming enclosure. That much said, we didn't lock it down - and other parties can work on connecting to it. However, the experience is unlikely to be as seamless as using a Razer Blade and Core together (for other laptops connecting to the Core may need rebooting instead of plug and play, frequent BSODs etc). It's not because we've locked it down - it's because there's a lot of work that's needed to make this happen and we've pioneered this. It's incredibly difficult - it's a feat of engineering both hardware and software. So coming to the price, we could probably have made it cheaper if we made it super big, plastic etc - it might be $300-$350 maybe. So yes - we designed a single block all aluminum chassis as opposed to plastic or even paneled aluminium. Further, the size is about half of that of other attempts at graphics enclosures. All this comes at a premium. It's a work of art. And for those who know the design philosophy of Razer, you'll know why we designed it as such. We don't design to price - we design to the very best experience. And it's $399 for Blade users - for those who already purchased a Blade Stealth, they'll get access to it at this price too. For those on a budget, there will be other companies will will make this in plastic, paneled aluminium etc, they will be much larger/bulkier, they will BSOD often etc - but they will be cheaper - so don't fret - these should come out in a year or two by other companies just like those who copied the Blade (and made cheaper versions) - so the option will always be there. So what do you get for the $50-$100 more? The best possible experience and the best possible design and - you get it a year in advance of everyone else (if they even make it).
