I've been looking at buying the Nvidia Shield Portable pretty much ever since it went out of stock on Nvidia's website and the price on amazon skyrocketed to $500 for a new one. I've been looking at used ones now and I've found one for $130 and I'm wondering if its worth it at this point. I've heard multiple roomers that Nvidia is working on updating the portable but at this point I don't know. I've personally never used one before but I've heard great reviews on it so I'm wondering if its worth the plunge for around $130-$200 right now.
