I am obviously not knowledgeable about computers. I purchased a retina MBP for my 15 year old daughter this past Christmas. I talked to the folks at the Apple Store (over the phone). They guided to me to purchase the 13 inch, 16 GB I7 but with only 128gb of storage. The lady told me since i also purchased a Time Capsule (2 TB) I'd be OK. I (believe) I now understand I should have ordered the larger storage. What is my best solution for her? I plan to purchase 2 more MBPs for my other 2 kids this Christmas and will buy the larger storage, but do not want to replace hers if not necessary. She has about 25 gb left on her storage now. Thanks for any help you can give...please keep it simple for me to understand.
