im trying to decide between a basic macbook (not pro) and just a powerbook on craigslist. why should i go with the newer macs (mac books) as oppose to the outdated models? i do freelance graphic design on the side. i dont need much power. just something to run photoshop, dreamweaver with ease and the occasional use of garage band. im a grad visual art student who does freelance graphic art on the side ... not a video or gaming person AT ALL. im looking at this.... http://dallas.craigslist.org/sys/391518920.html and this... the the Refurbished MacBook 1.83GHz Intel Core 2 Duo - White model trying to decide. what sayeth you all? should i just get a new mac? what kind of things will i be missing out on if i go with an older outdated model? anything above is better then what i used to have which was the old school tibook 667 (2001).
