I had a SB2 15 inch core i7, so maybe a little extreme, but the tablet alone generally performed poorly in battery and Microsoft was always a little optimistic on battery estimates. The hinge on the studio is a little fragile but also damages the keyboard deck (not the keys themselves) over time unless you are super careful. They also continued compromised choices in favor of the design over the use, the cpu is actually very poor for its class and they seemingly have no interest in updating it. I just wish they would just decide to build a dedicated GPU Surface laptop or a Dedicated GPU Surface Pro rather than halfway steps.
