People want usability, stability, reliability and same or lower costs. Not 'innovation" of itself. Instead we have a version of windows that isn't what is wanted (people just want an updated XP) and stupid ill thought out Intel security.
Battery life? Well, nice, but if you really care as a user you might be taking a spare pack... Oh I forgot, to make some of these machines stupidly skinny so no optical drive can be fitted the battery is glued in.
Unless life is 10 hours with Screen lit and disks whirring, do people care if it's 3 hrs or 4hrs? On a decent size and resolution 15" to 17" screen a lot of power is the screen.
Honestly I don't see much "Innovation" on laptops giving me a much better one than I bought in 2002. I don't care for a skinny one with only USB ports and ethernet if lucky, shiny instead of matte screen, no optical drive and 17" wide to get 1080 vertical resolution instead of the 1200 vertical resolution on a 4:3 15" screen.
There are some high end "retina" resolution models, but you need 17" rather than 15" because 16:9 instead of 4:3. I only watch video on a TV. I use a laptop to create stuff.
