Very happy.
I agree, far too much negativity on these forums... but then it's like that on most forums or review sites. People only take the time to post if they are really happy or really upset about a product... give you a skewed result.
Here are my favorite things about the SP3 (and to some extent Win8.1):
Slim and Light: This thing is crazy slim. I have a friend with SP2 and i always envied him, but the SP3 is unbelievably better in this department.
Charging Port: How cool is this?, i've used dozens of laptop power cords over the last 15 years and this is the best. My last laptop got yanked off a desk and cracked the bezel by a wayward vacuum, that wouldn't happen with SP3.
Touchscreen: I've had 3 laptop/tablets and this is the first one that i've left the touchscreen enabled (i just used pen support before). If you have Win8 you need a touchscreen, and vice-versa.
Screen: How gorgeous is this screen? I'm not one to choose form over function, but wow, i don't think i could go back to a normal laptop display.
Magnesium shell: Premium build here. Cool to the touch. Looks like brushed aluminum but better. At first i was disappointed it wasn't black like the others, not now.
Power Brick: Best i've seen in a Windows laptop. It's small, but long enough. And includes a usb port for another device!
Win8.1: I'm an IT guy, and while i've played with Win 8 before this is the first time i've really gotten into and i am impressed. More than impressed i'm having fun! The learning curve is high but the rewards just keep coming. The more time i spend with it the better i like it. I can see how people could get frustrated, but c'mon, Windows hasn't drastically changed since 95 and if people give it a chance they will see an OS brimming with cool features. I think Win9 will be phenomenol.
Picture Password: Try this!, it's cool and fun and innovative and fast and simple.
XBox Music: I'm not much into music, but this app is crazy good. And i can use it on my iPad and my Android Phone. How did i not hear of this before now?
