So huge update on this thread. I did indeed get the Ally with the Z1 Extreme. I ended up returning though and I am going to detail why.
1. The screen is too small. I tried 40K Martyr and you could barely see the characters.
2. Not full PC support. I tried Grim Dawn and no button or movement would move my character. I could install a mouse but that defeats the purpose.
3. It has less battery life than my Gaming laptop.
4. The Storage is paltry if you are a PC Gamer. 512GB is nothing today. I know you can get 1 TB but that is another $300
5. One USB C port. I have one of those Expander adapters. I can charge the Ally through the USB C port on that and attach storage via USB A (I formatted an old 1 TB 2.5 laptop HDD. However I cannot use my USB C NVME adapter. When you combine that with the 512GB of onboard storage not having access to NVME via USB C is not cool.
6. AMD software is not AMD software. If have an AMD card and like to tinker around there are a ton of settings in AMD software that are a joy to use. However Asus have their own OEM version of AMD software and you do not get aceess to that but have to use Armoury Crate to adjust GPU settings. I even went so far as to get the 7840U drivers from AMD but it could not find a supported APU.
Maybe a Steam Deck might be a different experience as that is not Windows. Even installing Windows on the Ally is no different than on PC at all. Including all the Windows things you say no to like Office 365. I could have seen it grow on me but that AMD software thing was a huge mitigating factor in my decision.
It is not all bad though. I had bought a 4TB NVME to update the Ally. Instead (Posted in another thread that I put it in my PC). The drives are abysmal at writes and I would not recommend them unless you already know that. So I moved City Skylines 2 onto it and it actually helps to maintain the frame rates better than the Drive I had it on before. To accommodate the new Drive I had to remove one of my old NVME RAID drives. I thought my WD AN 1500 was dead so just for my own curiosity I put my old NVME RAID in there. When I turned on the PC and went into Disk Mgmt there was 4 TB of unallocated storage waiting to be formatted. It seems insane to me now that I have over 28 TB of Flash NAND storage in my PC. Unless TPU wants to keep the vote up or the handheld conversation going here this thread can be closed.
