Last night I installed a build of that Surfer OS on my Hacintosh and decided it was a good time to roll up a fusion drive and a larger TimeMachine volume.
I was annoyed with my timing because I could have ordered the 3TB disk off Amazon, but then I remembered that Bestbuy will do a price match, and the Amazon app on my iPhone makes it easy to scan barcodes and comparison shop. Saved twenty bucks and walked out with it same-day. Hard to hate that.
