Recieved my WIN about a week ago. Ever since I have been bringing it to work, something I never would do with a 3ds or ps vita. People are blown away that I have a 5.5 inch W10 laptop lol.
Seems my device is flawless. Ran everything I tried without adjusting the bios or intel settings. I have since tweaked it to run full tilt and its a formidable little handheld. I've ran Dragon Age Origins, Valkyria Chronicles, New Vegas, Ori and the Blind Forest, DMC, Portal 2, Tales of Symphonia HD, Enslaved, and a few others perfectly. Dolphin is not really playable unless you really tweak it and get the PAL versions of lower spec gamecube/wii games which is dissapointing but expected. Maybe with a more powerful refresh down the road. I have yet to test PS2 emulation but I'm happy with Steam, PS1, N64, and GBA.
It's honestly surpassed my expectations in all aspects. I love the keyboard since games like DAO don't have controller support (the WASD d-pad is a Godsend) and the D/X input and mouse mode switch is a clever way of going about controller issues. In DMC for example X input wouldn't work correctly for whatever reason so I used Direct and customized my controller. If one doesn't work another will.
The only complaints (not really even complaints) is that it does get hot. No crashes, lag, or freezing from it but its as hot a Galaxy pre explodemon. The fan works really well surprisingly, you can feel extremely hot air being pushed out the front vent. Another fan on the right side would be perfect and maybe some vent holes above the keyboard to let the heat trapped there escape out. Otherwise just...
1)Raise the internal storage to 256 GB
2)Add clickable analog sticks
3)Better SD card reader
4)Add a second speaker and move them to the left/right of the screen
5)better cooling ala a second fan, vents, and a better heat sink and thermal paste
6)A bigger battery even if it added a 1/4 inch to the device's thickness
Really its all stuff an updated model will prob include. The battery life I get is about 2 hours for the most intensive games and maybe 6-8 for web browsing and letting it sit idle. The wifi is blazing fast. Downloaded 12 gb in 10 minutes of so. The screen is sharp with good colors, all in all its as perfect as i imagined it. I will test many more games and let you guys know the results.
