It seems to be quite impressive device, but also expensive.
It's a shame that GPD after GPD Win 1 completely abandoned this price tier and went very high with GPD Win 2 (and now with GPD Win Max). I really liked the fact that first GPD could be bought at the price (approximately, depending on the shop and discounts) of Nintendo Switch, and IMO it was much, much better option than so highly praised by US Switch. Plus the price tier which could be considered as "maximum" for mobile device for gaming, affordable for wider audience. Well, ok, "relatively" affordable, but still, definitelly much more affordable.
Price of Win 2 (and now Win Max)? It's only for passionates with well stuffed wallets. There are rather no chances to make it a popular alternative for other gaming handhelds. A shame, in my opinion, because I personally think that I've never found any more satisfactory handheld than GPD Win (mostly due to impressive games library on Windows).
I've bought GPD Win 2 some time ago with splitted payment, but I doubt that I'm going to decide on GPD Win Max.
