When Surface beats the M series Mac's I'll revisit, as 4-5 hours is not remotely close to what I need or now used to. Microsoft was on the right path with the Surface Book but dumped it in in favour of pursuing a worse performing MBP clone.
TBH Surface has rather fizzled out into much to do about nothing. At this point Microsoft really needs to dig in and go...
Q-6
Yes, this. It's why I have been avoiding it. Six hours is not a full day, and I need a battery capable of a full day. Ten hours would be fine. I am spoiled with the MBA these days on battery, but I still like the SP's form factor and versatility.
Yeah see I need like zero battery life like 95% of the time. I use my SP9 at like 2 different desk setups so for me it's just fine. And when I travel, that is enough time. I lower the performance and brightness and get like 6 hours so it's all good for me. That said, yes, it is absolutely the one thing I have thought about with the upcoming Snapdragon X Elites. The battery life! I can't wait to see how good it is! Of course the possible performance boost helps as well, but really with what we are doing on ultralight laptops, which is what the surface pro kinda is LOL, that is secondary to me.
