I like it overall but I have an issue where the battery drains crazy fast while sleeping. So I have it set to deep sleep, but that means it takes more than 15 seconds to wake up. This seemed like the perfect opportunity to get a new mainboard, but the new mainboards don't support my RAM... Which I went all out getting 64GB of. Don't want to throw that out, and don't want to buy another 64GB.. So now upgrading what should be just one component means almost buying an entirely new machine.
