The faster based on specs fuel innovation is looking at it thru a 1990s glasses. PC makers don't get it.
What is innovation? Apps that do new things, smaller, power efficient, shareable work flows, cloud integrated, high dpi, more mobile, better asthetics, etc
Compared to phones pcs suck!! 100 dpi in 2015 wtf . Bulky plastic, mechanical disks, etc
Office 2016 you quote? HUGE upgrade. Shared editing in real time with integrated Skype and chat is sweet for college students and groups. You can write a paper in real time and see others writting while having a video conversation. Functions are now searchable too. Yes Google Docs ripoff. :-)
I own a surface 3 pro which slashdot tees LOVE to bash as the coming of the anti christ with systemD as it's prophet. Truth be told it is night and day compared to a bulky core laptop with battery life and boot up time thanks to ssd and efi booting. Metro actually works. Lenovo yoga, HP convertables, and surface pro rock.
