Hey guys.. I think im going to buy my first mac ever.. Im nervous lol.. I will probably by an ibook.. not sure yet of the 12 inch or 14 inch... I need to decide should i get it now, or in a couple weeks because i thought new ibooks were coming out at the mac expo? ALso, should i buy it from mac? I will use the government disount. I will not upgrade the ram from them, i will upgrade it myself to 768. I will also bump the hd up to 60. Id also get bluetooth. Whens the next os coming out? Is there anything else i should no becauyse i have never used a mac before. I do some photoshop and internet.Also can i use the gvt. discount in a physical store?
