I like them too. I didn't have much trouble with the old system, but the new scheme is more in tune with how other games are played, namely the battlefield series from Dice.
It still retains the sim style to it, though. The more realistic gunsights are a good change, and a much needed improvement to the audio by having a turret rotation sound is long overdue.
I also found the full speed and full stop shortcuts after trying it for a while. Shift-W and Shift-A. I use them quite a lot.
I can't help but think this game is on the verge of becomming a contender to a true virtual battlefield. I could even see infantry (or infantry squads) implemented as a playable unit, but that would really need it's own discussion and I won't post that stuff here.
