Getting ready to purchase an ibook 12". Uses will be internet, email, downloading music (ITunes), Quicken/Quickbooks. There might be some light work on MS Office type programs but nothing serious. This computer will be strictly for personal use. If I upgrade to 768 MB of RAM and 60 HD is that sufficient for my uses or should I increase the HD to 80 and/or the RAM to 1 GB?????? Salute to all of you who are working today, especially those in retail.
