I can't say how happy I am with the SP3. I measured the screens and compared to SP2 it has 37% more surface area. The SP3 screen feels much larger than the SP2 and also the image seems more close to the screen surface, the overall display quality is better. But the best thing about it is the 3:2 form factor. I always hated to use a 16:9 or even 16:10 screen for my work (programming) but at that time there was nothing else available that ticked all the required boxes for me. Even now, there are very few hybrids with 3:2 or 4:3 form factor. The thinness (which I didn't care for in my decision) is also a vast improvement. Combined with the new form factor, I can finally use the SP3 as a tablet without feeling some "awkwardness" related to thickness and screen space limitations. But my use as a tablet is about 10% of the time. Black Friday brought out some good deals in SP3 + Type Cover 3 in Europe, so I took advantage of an i5/8GB/256GB to replace my (identicall specced) SP2. Of course, there is a significant financial hit involved in the SP2 to SP3 process which makes many people reluctant to upgrade (including me), but in the end I think it was worth it. I can see myself using this for a long time (unless it breaks, of course - knock on wood). I can also see myself skipping the Broadwell Surface Pro refresh and going straight to SkyLake when available.
