I will appreciate any advice on my situation. I am an educator and need to buy a computer so my kids (7-9-years-old) can have access to one. I currently have a black MacBook and love it. My debate is that I could get them a 27" Imac or I can get a 15" MacBook Pro for me and give them the 13" - I would buy a display for it. Given my line of work, I am able to write off whatever computer I buy. I am perfectly happy with my 13" MacBook Pro but would no mind at all to have an excuse to get myself a new one Could you advice me what you think may be the most cost/rational decision? Also, although I qualify for the educator discount, what would be the most cost effective way to buy it? Through Amazon? Apple Store? I would ideally like to take advantage of any zero financing offer. Thanks.
