I bought a Surface Pro 4 fanless m3 with 128gb version last week on sale from BB for 600 using an EDU coupon they give out. All I can say is, I sold my ipad Mini 4, Dell 7000 Android tablet, Dell i7 2-in-1 laptop, and a Dell Venue 11 Pro tablet PC. That should tell you how good the Surface is, no point in messing around with all that other stuff anymore. In fact, I even bought my wife a smaller Surface 3 with cellular for her to take when she's on the road.
Those iPads and Android tablets look like a joke compared to the Surface and the sad part is, an iPad and a Galaxy Tab S2 are almost the same price as the Surface.
