pdb1: Are you kidding me ?
No, I'm not kidding. Trust me, when I'm kidding, I"m a lot funnier than this! :-)
I don't play the PC/web version consistently enough, so the easiest way for me to know is to ask. All of my ranked rounds have been played on an iPad. Now, I have played a few practice rounds online, and I just haven't seen big differences on some of the stuff you mentioned.
For example, there's a decent mini map on the mobile version. And I've never noticed any real differences in the camera views that are offered. Additionally, I've never thought that higher precision shots can be made on the PC, even with a bigger monitor as opposed to the iPad. At least, I haven't had problems with that aspect of the game on the iPad. Even so, I'll admit that the biggest monitor that I tried playing it on was a 24 inch. How big of a monitor are you using?
Yes, mouse precision helps with hitting the ding on the PC version. I'll grant you that. Hitting the ding on the iPad is more difficult. But the forgiveness of the clubs on drives and approaches is better or more forgiving on the mobile. Nevertheless, the information regarding green speeds and direction are much better on the PC. As someone once noted, if they could make their drives and approaches on the mobile version and then be able to easily switch to the PC to putt that would be ideal. :-)
Regardless, I'm not asking you to convince me. I just wanted to know why you claimed that the mobile is "very crude and primitive." I simply don't agree.
