As someone who has used the Snapdragon X Elite (12 core Oryon) Dev Kit as a daily driver for the past year, I find this exciting. The X Elite performance still blows my mind today - so the new X2 Elite with 18 cores is likely going to be even more impressive from a performance perspective! I can't speak to the battery life, however, since it is dismal on my Dev Kit ;-)
How's the compatibility? Are there any apps that don't work that are critical?
The Prism binary emulation for x86 apps that don't have an ARM equivalent has been stellar with near-native performance (better than Rosetta in macOS). And I've tried some really obscure stuff!
