I ended up getting a 15" Surface Laptop with 32gb RAM, 1 TB SSD. So far so good, although I haven't really had a chance to put the battery life to its full test. I was a little bummed that this model only seems to come in black, but not a big deal really. Its also a bit heavier and larger than my previous Lenovo, so that will take some getting used to...part of me wonders if I should have just went with the 13.8" model.
Otherwise, this thing is really nice - love the build quality, speed, facial recognition unlock, and (hopefully) really long battery life! Thanks all for your input.
