Thanks for covering that up, i will add them again but a bit better than they were before.
Yes, your trackpad is a personal choice thing.
For me im using the standard trackpad with latest VoodooPS2 from Acidanthera and it's perfect for the non upgraded trackpad. All macOS gestures, force touch with the pressing, it's like a real Apple Force Touchpad, it's really nice.
I may not upgrade it on my X240 at all, at least not for now.
I will only upgrade to the 1080P Display and this laptop is absolutely perfect for my needs, im so glad i picked it up.
10 hours of battery life, backlight keyboard, 4G LTE (working natively on macOS), This thing is really satisfying !
