My initial impressions:
After a rocky OOBE (multiple crashes, including one hard crash that made me question if the hardware was bad) - which included a lot of updates - everything is up and running! For the most part, everything works fine, and the machine feels very quick despite it being the lowest-end Elite SKU.
The only compatibility issue I've run into so far is Anaconda, and even that installed and somewhat works. I do think there is an issue with SmartScreen or something, a lot of apps can't be downloaded in Edge, complaining about a failed virus scan. No issues downloading these applications with Firefox, so I am guessing this is an Edge/MS issue.
Overall I am pretty satisfied with the performance. The big questions are: How well will sleep work (I hate that this is a thing on Windows laptops), and how long will the battery last.
Haven't been able to play with the NPU much yet, but I am looking forward to seeing what can be done. At the moment it isn't terribly useful without Recall. I cannot imagine what it must have been like at MS for the last few weeks trying to fix up Recall to get it ready for launch. It really is the killer app for the NPU, IMHO. Generating pictures is fun (and I know a lot of people have subscriptions to online AI services so I am sure it is valuable to some people) until it isn't, and I don't do video calls.
Edit: This is on the HP Omnibook X
Edit2: It isn't SmartScreen or Edge, it was Mcafee! After uninstalling Mcafee, including the Webadvisor app, which is separate from the extension and the main scanner, downloads in Edge work fine.
