No. It's not going to be radically different. I've had mine for nearly a year now. It works very well, you can get free apps that are useful (check out the App Store), and you can adjust pretty easily. I think you will like it better than your PC. I sure like my Mac more than any PC I've ever...
I sometimes hold off. But when I finally give in, I cum so hard and so much. Usually, it's once or twice a day. It depends on my mood.
If I feel terrible, like when a girl says no to a date, I hold off for a while.
