I went from about 3 hours of battery time on a high end windows laptop doing my design workload to about 10 hours with the m2 pro. I still don’t know if I’ll stick with it long term, and I still much prefer to work at my windows desktop, but having a fast, battery sipping browsing/streaming laptop that can turn into my main workhorse when I’m out and about has been great. Plus the Unix environment means I’m not spinning up arch vms when I’m programming anymore.
Windows on ARM has existed for years btw, complete with x86/x64 emulation. The emulation is nowhere bear Rosetta levels unfortunately, which is the main thing holding it back.
Battery life and sleep/standby/resume times are amazing on it.
Microsoft need to get their own chips made like apple though, as using a slightly modified mobile phone SOC isn’t fixing the performance level to match apple.
