On July 17 I am purchasing my first Mac computer and am looking into purchasing the entry level MBP 15" 2.4ghz I5 processor and I have a few Questions that are a bit concerning for a new mac switcher. I appologize if this thread is out of place or to generic but this is my first post on MR Forums so i'm a bit skeptical on everything. I performed a search for some of these concerns and although I read many threads, none of them properly answered my issues. 1. I am looking for a laptop in the mac like that properly fill my word processing, web browsing, and light photo/movie editing needs, but more importantly I am looking to make this investment last me through my senior year in high school and through 4 years of college. Is the MBP 15" 2.4ghz the right computer for my needs and have a moderately functional longevity or, should I consider another MB? Will MBP last 5 years?? 2. Concerning the MBP 15" I have read a few thread on here about "All" MBP I5s/17s having terribly bad freezing issues. Is this rumor true? Does it really Affect all MBP I5/I7?? Should I wait to purchase a MBP?? 3. As a switching user I have done alot of research on how to properly manage and maintain a mac. I have heard that Onyx is a very good program and that macs are virtually resistant to virus. Is Onyx all its cracked up to be and do I need it to preserve this laptop for my hopeful 5 years? What is a good AV for scanning files if I want to give a friend a file without being careless and oblivious to his ability to contract viruses from my files?? again I apologize in advance if this thread is out of place or to lengthy in its scope. Please bear with me as I am not only a new mac switcher but new to this Forum. Also, any tips for maintain a mac would be greatly appreciated!
