Hi, I'm looking to purchase an iBook (used, needless to say). I am a student in the last year of middle school, and I need something that I can use for the internet, reports, slideshows, etc. My current spending limit is $250, and I need wireless, at least 512MB of memory and at least a 700MHz processor. Could someone provide me links to a site that has an iBook that meets or exceeds my demands? Thanks so much, I really appreciate it! s are the best!
