我選了x270如下 (NT26,595)
1. i3-7100U
2. OS (does not matter, clean install later)
3. 12.5" (1366x768)
4. 4GB ram
5. HD 620 (build in)
6. English Keybaord (backlight)
7. Finger scanner (not necessary, but could not be excluded)
8. 720p cam (not necessary, but could not be excluded)
9. 128GB SSD
10. Smart Card Reader
11. Front 3cell 23.2Wh battery.
12. Rear 6cell 72Wh battery.
13. 45W AC (this confused me, there is additional USB C type, what for?)

低效能, 高續航力配置~ 不過, 今年沒預算 =.= 要買也是明年.
