Dear friends!
In which device is the most comfortable and best for long typing keyboard?
1) Surface Book
2) Surface Laptop
3) Thinkpad X1
4) MBP 2017
Best keyboards Surface Book & X 1 Carbon. The Lenovo is also the most modular, allowing the user to service and upgrade. Surface Book same as Apple will need to be returned for any repair and or service. I would recommend that you only purchase whats officially supported to ensure you have cover in the event of an issue.
You just need to check to see if it's officially supported, FWIW my own Surface Book I bought in China and comes with a 2 year international warranty from Microsoft directly this it the type of coverage you need. I would also be surprised if Lenovo did not offer the same. Thinkpad X 1 Carbon is listed on Lenovo's Russian site, so it may be beneficial to contact Lenovo directly.
Apple's support shines when you have an Apple store in your vicinity, if not same as others you need to mail and or call, equally Apple's support is generally accepted as the best.
