This is my first post and question. I love forums as they seem to provide the best info out there. I am and have been a PC user since the '70's and am contemplating moving away from a Microsoft OS. I own an iPad and love it. However, the iPad is more of a travel/sit on the couch toy and not my main means of computer usage. I do some online gaming that requires flash/java, can I accomplish this on an iMac? I am contemplating purchasing the new iMac with the i5 core 21.5" screen. What kind of transition/growing pains can I expect? Will I be disappointed? Thanks.
