Sony Xperia Z4 Tablet review: the new netbook? | The Verge

"HE Z4 TABLET SOUNDS GREAT IN THEORY, BUT THE FINAL PRODUCT DISAPPOINTS
Yet again, I find myself deeply frustrated by Sony’s failure to live up to its own expectations and produce a cohesive product. The company’s ideas are not bad: there is definitely a class of more conservative mobile PC users that demands a real physical keyboard and Microsoft Office compatibility. Such people can be very adequately served by the Surface Pro 3, but they don’t strictly need a Windows PC. An Android tablet — especially one preloaded with Word, Excel, and PowerPoint as the Z4 is — can fulfill most of their needs, while costing and weighing less. If I was heading off to university this fall, I’d definitely consider getting a super thin device that can be both my YouTube video player and my modernist take on the netbook for taking lecture notes. Sony's premise is sound. Its execution isn’t."
