I just got the 16GB/i7/512 with 2 year warranty from Costco for $1599. And I agree totally that it's an amazing machine! I have left it running W10 for now because I don't want to have to modify the DSDT for S3. Modern standby on Windows is magical - instant desktop after lid opening with the fingerprint reader! I wish it had better speakers though and I still feel like the low power CPU in a thin package might get bogged down when thermally throttled compared to full wattage one in a bigger config. But so far no such problem.

While I did end up doing that (it wasn't as scary as I thought), turns out just adding `acpi.ec_no_wakeup=1` is sufficient on many distros (I presume ones with recent kernel/systemd versions, older versions seem to require hitting power to wake up). > I wish it had better speakers though I find the speakers fairly comparable to my old MBP, fwiw. > and I still feel like the low power CPU in a thin package might get bogged down when thermally throttled compared to full wattage one in a bigger config. Yea, kinda mixed feelings on this. I really like how cool/quiet it runs with the default config, but you're right that the throttling is fairly aggressive. I mostly went with the i7 for the L2 cache size rather than max freq so it doesn't bother me too much. You can override the throttling thresholds a fair bit. The whole machine is fairly hackable (in the good sense). I plan to play around with underclocking at some point to get a few extra hours.

  I find the speakers to be awful, but I just use headphones most of the time anyway, so nbd. I have the last gen, so may be different. I'm curious how you tuned the thermal throttling, though!

TL;DR Booting Linux the throttling triggers at much lower temp than on Windows. Fixed by overwriting some MSRs I think.

      Sweet, thanks!
