Following up my keyboard issue thread, I went to the Apple Store Genius Bar and compared my device with a showcase model, and the "genius" played it off as if they felt the same. I accepted her valuation, but told her I'm expecting no issues whatsoever if I'm paying $1600 for a device. She goes on to say that they don't carry 8GB RAM models in the store, and I need to ship it back out to Apple? I'm unsure whether she was just unwilling to help me with the transaction (after driving half an hour out for the appointment 🙁), so please help me out if anyone can. Thank you.
