Sorry just noticed your post.
Yes, it looks unlikely they'll update drivers. When I first purchased the Forte I was using Win 7 and had no issues. I used it with two different laptops on Win 7. So that varies with hardware apparently. Both those laptops eventually had Win 8 and it works with those. One is currently on Win 10 again no issues. I also have used it with a Macbook Pro with no troubles. Who knows if Forte will change the driver if it no longer works with future Windows?
As for comparison with a Apogee Duet Ipad, I don't have one to do any comparing. If I were in need of replacing it, I'd look at the Focusrite Clarett series as they use the same circuitry and ADC/DAC chips as the Forte.
