Long time windows user. I have decided to switch and my heart is set on a 15 inch PB ALU. I am thinking of either refurbished or Edu discount (new). Refurbish gives me additional $ 200-300 discount depending on config. but its not new. My questions about refurbish: 1. Does it come with all the software and disks as new and is it really that important as long as I am getting OS 10.3 install/restore CD and Panther upgrade CD. 2. How easy it is to upgrade memory? I read somewhere on this forum that there is accessible and inaccessible slots for memory card. Is it true? Refurbished I am considering comes with 256 mb and I will certainly expand it but will I have to get it done professionally and will it void warranty?
