No effort
1. Microsoft has simply made buttons 4 and 5 less "floating".
2. The mouse is, it seems to me, heavier than before, whereas the trend is towards lightness! 140 grams? SERIOUSLY? Double the current standard!
3. No improvement in the scroll wheel, which doesn't stick out enough from the mouse shell which makes it harder to grip.
4. The grip remains as it was back then, excellent (for VERY large hands!)
No interest in 2022 for gamers.
Are they going to release an IME 1.1 with no improvements either?
