It may be software fixable, but it's still beyond frustrating that in 2014, Google would allow its flagship tablet to launch with serious lag issues. Do they want to grow the Android tablet space or not? Because it's Apple they're competing with, and Apple would never let this happen. It's not 2008 any more - tablets aren't a first-generation device with expected teething problems. This bread and butter user experience stuff really needs to just work.
Apple release garbage at times, they have had quite a few recent software launch issues. Software updates that break basic phone functionality, The Fappening etc.
