ThinkPad X1 Carbon (3rd Gen) 2015 Touch vs Non-Touch

[schmoove]

Hi there,

I am about to purchase a new ThinkPad X1 Carbon (3rd Gen) 2015 and am contemplating on getting a touch version or not of the QHD (2560 x 1440) IPS panel. The touch aspect is not too important to me and I would be willing to pay the €100 surcharge only if I won't have to expect any abundant downsides. I am wary about some possible disadvantages, which I could not confirm anywhere and I am hoping someone reading this has some answers to the following questions:

Does the X1 2015 Touch weigh more than the Non-Touch?
If so, how much heavier is it?
Can both screens achieve the same maximum brightness?
Are both screens comparibly glare-free?
What about power consumption?
Does the Touch consume more power? If so how much more?

OK, here are some answers to my own question, taken from the official specs listed in tabook.pdf.

Does the X1 2015 Touch weigh more than the Non-Touch?
If so, how much heavier is it?

WQHD = 2.877 lb / 1.305 kg
WQHD Touch = 3.175 lb / 1.44 kg

Can both screens achieve the same maximum brightness?

WQHD = 300 nits
WQHD Touch = 270 nits

Are both screens comparibly glare-free?

I couldn't find an answer.

What about power consumption?
Does the Touch consume more power? If so how much more?

Max battery life:
WQHD = 9.9 hr
WQHD Touch = 9.9 hr
