T450s -- Display, NGFF SSD, Smart Card Reader, and m.2 SSD slots

[scottkeen]

I'm looking to order a T450s and have a few questions about options when configuring the order:

http://shop.lenovo.com/us/en/laptops/th ... ies/t450s/

1080 Display -- Does anyone know if the 1080 display (non-touch) is made by LG or AUO or someone else? There was extensive discussion about the T440s, and people got different brands and the AUO was the preferred brand.

16GB m.2 NGFF SSD -- If I remove this option, and want to add a 3rd party compatible NGFF SSD later, can I do this?

3rd m.2 SSD Slot -- The options are None, 3rd m.2 SSD slot, or Smart Card Reader. If I select the Smart Card Reader option, can I later remove the Smart Card Reader and use it as a 3rd m.2 SSD slot? Or, if I select 3rd m.2 SSD slot and later want to use it for a Smart Card Reader, can I buy a Smart Card Reader and plug it into the slot?
