Yeah, “ARM-based Linux laptop with 22h battery life” is much more interesting to me than “Windows 11 ARM-based AI PC”. If the TPU can eventually be utilized by open models under Linux that’s just a cherry on top.
Acorn tried very hard, but without a critical mass of software ported to the platform it was nearly impossible - Apple was the only other platform that survived.
Now, with open source, it’s easier to open up a place for other architectures. Android and iOS took over a lot of space traditionally reserved to Windows and Microsoft is not oblivious to that fact.
Laptop battery life estimates outside of Apple are downright criminal. I'm still bitter over the time I bought a fully loaded Sony Vaio which had an advertised battery life of 11 hours. When in actuality, I only got less than three hours of battery life and complained, they explained to me that they meant it gets 11 hours of standby mode with the lid closed. I only made the mistake of buying a non-Apple laptop one more time with a fully loaded XPS which could barely manage 4 hours of battery life. I honestly have no idea how anyone can put up with non-Apple laptops. It's pure garbage out there.
2-4 hours sounds wrong. Were you mining bitcoin in the background?
"Battery life on the ThinkPad X13s will depend on your workload ... and while you might not get close to the 28 hours that Lenovo touts in its own testing, our testing with PCMark 10 got us an amazing 15 and a half hours..."
I was working on a Rails project and had a YouTube video playing in the background, its a 49whr battery and the CPU can easily burst above 15w and usually sustains around 7w plus backlight and all the other components of a laptop, a sustained power draw of 15w while doing development work isn't unusual.
