Received my new GPD Win2 direct-from-manufacturer yesterday. At first touch, it is more like a Rolex than a Timex. Very nice quality and feel. The processor is VERY FAST, like an older laptop i7-920XM Extreme or i7-2ndGen-series.
As soon as I turned it on, I decreased the volume to 66% and brightness to 0% thru the keyboard to make sure the parts last as long as possible. I connected to my 5GHz wifi, then I updated all of the Windows updates to current 08-2018 Win10 1803. And, finally, installed the newest 08-29-2018 Intel Graphics drivers.
I synchronized an external Bluetooth Apple Mac Keyboard and Microsoft Bluetooth Mouse 3600 and Xbox One bluetooth-enabled controller easily to the onboard Bluetooth 4.2. I also am using a 400GB SanDisk microSD A1 card and Samsung 128GB USB ultra-low-profile flash drive. Micro-HDMI works great on my TV.
In some emulators, the proper rendering method fullscreen to use is OpenGL, instead of 'ye olde' DirectX 8. DirectX 8 fullscreen can sometime chop-off the graphics on-screen.
I do get a "sticky" A-button while gaming. This isn't too important because most emulators allow re-mapping of controls. However, this is the disappointment of the unit I have. It is the only button I have that sticks, and I have played a lot of Contra, Castlevania, Gradius, S.T.U.N. Runner, and Gauntlet: Dark Legacy. It seems if I push down on the metal frame of the system with my thumb slightly while pushing the A-button in, there is no sticking.
I do not care that there is no built-in rumble on my post-Aug 20th system. No rumble is not a problem. There is probably a good reason why they had to remove it.
Overall, it is better than expected, because I had such fears of what I could receive from a fearmonger that overexaggerated any potential problems. It is very much like a dream in the palm of my hand, like Phawx remarked in his review. It is every emulator game I have running very well and portably with very good battery life.
The GPD Win 2 is nothing I regret buying. It is very fun. The portability is where it's at. Everybody I have shown it to thinks it is "so cute" and interesting. I think the 720p resolution is not too small.
I have no reason to ever disassemble this machine by myself, so anybody that does that must know about the fragility of tiny stuff, and have steady hands (that I do not have), so I hope there are never any problems with this machine. (I'd dread having to ship something with Lithium batteries overseas by myself.) I also have not run any modification through Intel XTU, because I have not had thermal throttling, yet.
