Hello all - The only true tablet-like Surface in terms of size/weight is the Go. If anything, getting it under 1 pound would be ideal, as even the current weight of the Surface Go is problematic for longer tablet use, especially for one-hand tasks like reading, or if you have a bad back and don't want to carry much weight.
With all due respect to the good folks at MS, I believe there may be confusion within the company about the Go. Is it merely small and light because it is cheap? A good option for some, but others like myself the answer is no, I want an even lighter laptop/tablet that has the more tablet like capabilities and feel, when used without its keyboard.
Next most important is a brighter screen, so the little tablet/laptop can be used outdoors at cafes and coffee shops. Some extra battery life would be a nice 3rd feature.
I would ignore the pundits who always call for smaller bezels, as you need a decent bezel to hold the machine in one hand. Similarly, speed/memory is less an issue than the above items, I think. In fact, I suspect the Surface Go 3 already has enough speed and memory for many of us. I use office, multiple browsers, etc. fine with the original Surface Go 1, but Office/browsing/reading is so difficult in tablet mode, I don't even bother half the time.
Thanks!
