Far better functionally. Better battery life, better CPU utilization. Sleep settings actually work. Actual support for touch gestures in the browser (Yes, Microsoft shipped their brand new high tech browser without gestures! That the last one had!). On screen keyboard that actually pops up in all programs, not just Metro ones. Far fewer random ridiculous bugs (such as the Windows store completely disappearing on me, causing apps to stop launching. Also for some reason Windows 10 seems to forget my Outlook settings every 3 days.). Touch targets that are actually hittable and dont result in endless frustration (task view, WTF).
