So it looks like GPD are exploring whether they can use the same liquid cooling heat pipe they use in some modern smart phones like the Galaxy S7.
Heat pipes are only useful for effectively moving energy away since they operate by evap and condens in a very specific range. A better solution that a pipe is the flat vapour chamber.
Those vapour chamber designs could provide a solution but in general they aren't cheap they will add an easy 20 dollars to the BOM. What you will get in return is a very even temperature profile since energy can flow into all sections very fast.
I'm myself more concerned with the key mapping in a windows environment. One of the great things about the GPD XD is that emulators were easily mapped even touch screen games were easily mapped to the controls with the software that came with it. The GPD XD did this incredibly well.
Windows however is a pain playing emulation games with a controller whether it is Dolpin, PPSSPP or PCSX2 it is a pain every time. Actually so much that it is usually less cumbersome to just use the actual console. (I no longer have a working PSP nor PS2 both are broken)
Another major concern is how usable windows will be on such a tiny screen. I've tried remote desktop streaming and both at low as well as high DPI it was completely unusable on the GPD XD. The GPD Win will have a similarly sized screen so I doubt this will work well.
I'm not sure how I feel about the keyboard I think the key spacing on my 2 in one tablet is already quite scarce (it's 10.1") besides this there is the key feedback which may or may not be good enough.
I think I'm going to still order one however because otherwise I will have to judge it by reviews again. The GPD XD didn't disappoint actually it was so very amazing everything did work out of the box only minor design flaws to me.
I don't really like the thumb sticks for example, they sometimes don't seem to respond well when I push them almost all the way but not quite into a corner.
Personally I would like to see the following upgrades worked into the GPD XD 2:
- LTE support
- 64 bit ARM SoC (Perhaps by that time AMD's Zen based ARM SoCs (K12?) will be ready) (or another Mediatek SoC that is fabbed on a solid 14nm process)
- Bigger internal memory (128GB standard would be a nice start)
But I'm not sure whether or not other people would want to pay extra for those. I would actually the GPD XD is pretty good for it's price and I wouldn't mind paying a bit extra to make it even better.
