Still in the process of setting g it up. But it updated right away to 10.5.5. screen looks great. Love the keyboard. This was bought NEW from Blutekusa on eBay for $1149 no tax, free shipping. It's a base gold. I got a very slick dongle with 2 usb 3.0 ports and type c charging port, a clear cover, and a slick looking case -- all from amazon -- for $50. So now it's not too different, except for the screen, from my 2014 vase 11" MBA. Will update with progress report. I had spent time at both the apple store and best buy playing with these since the introduction. besides the retina screen. I fell in love from the beginning with the keyboard. I'n a VERY fast two finger types, so its perfect and I love the tactile feel. Later.
