The entire premise of modern computing is built around deterministic memory. ECC in laptops very long overdue.
Shame it's released by a company which cannot be trusted anymore. I know the bigger blunder (SuperFish) happened in consumer laptop, but all things considered, I can't trust Lenovo any more. That means I won't buy anything they make. I miss old Thinkpads.
Is there any serious laptop manufacturer left at all? A company that builds good hardware, allows user replaceable battery / memory / disk, and doesn't include any crapware, or things you can't disable (like secure boot, Lenovo style hard disk file replacement, etc.).
At least 2015 Macbook Pro 13" is pretty fast and light. I also love the display. Wifi is pretty snappy, download speed from internet is over 250 Mbps, which is enough for me.
I'll swap the internal SSD to 1 or 2 TB model once they become available.
Its ability to drive 4k monitor at 60Hz is also nice. I know it's not enough for everyone, but 4k is all the resolution I'll ever need from a computer display.
I'd personally only do this if the 1/2 TB models were also SSD. OSX is so IO heavy now that any machine without an SSD feels like it's wading through molasses to get anything done.
