Welp, I cancelled my original order, and ordered the middle 16-inch model because in the end I realized I wanted the 1TB SSD. When the store opened, I was ready to get 1TB but I got sticker shock so I stepped down to the base 16-inch, which had the 512GB SSD. The waffling made my delivery date Nov 2-9. However, all day I was still debating with myself over the SSD size. I can attach external drives, I told myself. I checked the usage of my current MBP, and figured I can live with 512. However, I couldn't stop thinking that 1TB would be better in the long run. My final conclusion was in a few years, I won't miss the extra money spent to buy the 1TB model; but if I stayed with 512GB, I would see that space available information everyday, and I would regret not going 1TB. It's a bummer that my delivery date is now Nov 10-17, but I can wait for the MBP that I really wanted. I will try not to kick myself for not ordering the 1TB in the first place because I could've gotten my order on Oct. 26. Anyway, thanks for reading. I know the people in this forum and thread would be the only ones to understand this situation.
