I've read through other posts and seen the disadvantages of buying used: lack of warranty, shorter battery life, it doesn't have the new Apple smell. Just joking. But, as a PC user and a business major, how much are these things really worth in terms of dollars? My dillemma is that I want a new powerbook. I'm looking at the 12" with SuperDrive, and after the Educational Discount it comes to $1400. Good deal. However, a friend wants to sell me his older revision powerbook. It's a 15" powerbook g4 1.25ghz for $1300. It has all the same specs: 512 ram, 80gig hd, superdrive, airport, bluetooth. So now, how much does the lack of battery or warranty really mean? Is this still a good deal? I'd like to make movies with this, and so the bigger screen is a major plus. But, it's 1.25ghz and 2-years-old. Any thoughts? Thank you very much.
