Hi. My younger brother currently owns a MacBook Pro 13" (Mid 2010). He uses it mostly for photo and video editing as he has a YouTube channel, and his hard drive is filled up with heavy applications like Photoshop and Screenflow. With Mavericks his computer is almost unusable; it is very slow and unresponsive, it takes minutes to start up and it often runs out of memory, so he would like to buy a new Mac. He would like not to spend over ~1400$ and he doesn't want another MacBook Pro because he says he needs a larger screen and he doesn't care much about mobility. Since the Mac Pro costs too much and he doesn't want a MacBook, basically he can only choose between a Mac Mini and an iMac. Which model do you think is best for him? And should he wait until October for new models to be released before buying one? Thank you.
