I've just about had it with the world of PC's. I recently purchased a Compaq laptop and in a few months it's totally bogged down with spyware, etc. I was also just upgraded to Vista on my office system and have never been so frustrated. This has led me to the world of Mac and I need some advice. I'd like to start slow and buy a small used system, but I'm so unaware of the terminology that I'm overwhelmed. Can anyone give me advice on a strong laptop that will do basic computing, email, word processing, photoshop, CD and DVD burning, wireless and travel well? I've seen iBooks for around $300, but they all have varying degrees of processor speeds, HD sizes, some w/ DVD burners somewithout... Any help is greatly appreciated.
