I personally live in a country where it's hard to get any small thing easily online: I'd probably have to order it online from USA, UK or Germany, get it processed by customs and then hope it'd work well. To reduce the costs of trying out more than one item, I'd probably order a few different ones so the shipping costs and customs costs are contained. Which means that I'd be spending $150+ on a screen protector that might not work.

Or I could just look for a laptop that has an anti-glare screen ;-) And a good keyboard.

Too bad new AMD-based Thinkpad Z series do away with a bunch of the good things from X1 Carbon (soft-touch palmrests for one), or I'd seriously consider them to be able to drop my desktop entirely (Intel iGPUs struggle to do full screen video calls on 4k external screens under Linux, I am _hoping_ AMD 680M would do a better job).
