Current Duo is the fastest phone I've seen - and after years trying wireless, ever since became possible, and thinking it was a must - - it's not. I've used Note for 10 years, S21 Ultra this year.
The Duo 2 will weigh 284 grams vs 250 now, compared to 224 for the Ultra (but which feels heavier!)
The Duo is easier to handle than iPad Mini - I don't see it as a "phone."
