Personally I don't necessarily have a problem with the throttling, I just enjoying understanding how my computers work and being able to squeeze every ounce of power out of them I can. While researching what exactly causes the throttling of my i7 SP3 and under what situations, I discovered that disabling connected standby brings back all of the old power profiles and controls of a normal laptop. I wrote a short script that lets me toggle it with a restart, and it lets me cap my Surface's power while running flash videos and doubled it's battery for doing so. I might not have stumbled across this if I didn't look into the throttling.
It is true that I don't notice any throttling under normal usage conditions (web browsing/note taking/video watching/network administration/programming) and I would never load a game for a reason other than "just because I can" as I have a powerful lightweight laptop that is better for purpose. Under benchmarks, I do see about a 15% speed improvement over my Surface pro 2, which is impressive given how much thinner and lighter the SP3 is. However, the 40% worse graphics performance benchmarks from my SP2 scared me for a bit, but after using it for a week I think its an acceptable compromise for the improvements they were able to make in the chassis, given that even with my SP2 I only loaded a game on it a handful of times for the sole reason of "because I could".
