I have to admit I never use trackpad - I always carry a Bluetooth mouse (keyboard as well with my MBP because of how terrible it is) and for couch surfing touch screen is king for me. I also had a yoga and would go for that X1 next - the versatility is amazing (bed/couch/travel media use in the reverse V position is 10x better than tablet and laptop) Battery life is about equal on this MBP - it's just a terrible CPU for a mobile device. But more importantly I use battery about 1-2% of the time - ergonomics are just not good enough for it IMO. X1 Yoga with an AMD CPU would be my ideal laptop but unfortunately it seems like AMD gets pushed to gamers and budget laptops still
