It's tax-free weekend in my state. [Edit: irrelevant now, Best Buy is offering better deals anyway.] These are my options: MBPr 13" 128GB 8GB - $1200-ish 2013 MBA 13" 128GB 4GB - $800-ish MBA I am stuck with 4GB. MBP has better I/O, possibly worse graphics performance with the display, but I get 8GB. 8GB MBA is possible from Apple, but would essentially be a $500 RAM upgrade.
