You have provided no specific example to anything you have stated. "Buggy" is not an example. "Somewhat limited" is not an example. "Staff having limited knowledge" is not an example. "Brick the device" is not an example. "More stable" is not an example. Hence, I have to question if you actually own a SPX.
After instilling the x64 bit emulator on my SPX, I'm now able to run my statistical software (SPSS and R-studio). Edge Canary Browser, MS Office apps (Word, Excel, PowerPoint, OneNote), Zoom, PDF annotating apps (e.g., Drawboard PDF), and Snapdrop all work great. So far, BatteryBar is the only app I regularly use that doesn't work.
The downside is that battery life has declined from 11.5-12 hours of continuous YouTube viewing (40% brightness, battery saver on) to 9.5-10 hours. Finally, Surface products are for white-collar professionals, not gamers, video/photo editors, or YouTuber tech reviewers.
UPDATE: After uninstalling the "KB5003266" update, battery life has returned to 11.5-12 hours...
@MSP2020 , did you manage to install 64-bit MS Office in x64 emulator? In reviews from December2020 it was mentioned as impossible to install. I have SPX, but because of work, I prefer to wait for official release of x64 emulator than install Preview Builds due to frequent restarts.
My experience with SPX is great, but, as stressed by many of you, if there is specific x64 app you absolutely need AND there is no x32 version of it, don't buy SPX. I even managed to work on video with Shotcut x32, even if it doesn't see Adreno GPU acceleration.
SPSS exists for x32. Microsoft Visual Studio is still x32 software, until version 2022.
With Java apps I found OpenJDK Java 16 compiled for ARM64 by Microsoft on Github. MSFT will also port it to M1 ARM64 Mac. Most of the stuff works for my PMOD 4.2 for OpenJDK 11 (www.pmod.com), when you just substitute jre folder with the one from Microsoft. Still there is some stuff written specifically for architecture, so it doesn't work there.
From x64 software I need, there is still Mathematica 12.2 and Matlab. Mathematica installs in WSL2 in Ubuntu Linux, but its kernel is architecture specific, so it doesn't start.
Yesterday I managed to install Docker on WSL2 with Ubuntu and run first container. Hopefully Matlab in container will work.
Lunux got GUI official support in WSL2 in Preview builds for x64, so I hope this will be here in 21H1 update also in ARM64.
I had hardware problem with SPX, it was rebooting silently if charger was connected in sleep mode in about 30% cases. I passed it to service, they confirmed it and I got a new one in about 10 days altogether. I also bought 4 years warranty extension. So don't buy SPX from doubtful sources.
I am university professor, so bought SPX due to weight AND battery life. There always will be a surprise. I have USB-C extension for RGB and HDMI displays and this thing is 15W! You can work on SPX only about 4 hours in such setup. I don't have USB-C monitor...
