Base Air is only 8 core CPU 8 core GPU at $1200 USD. 18 hr “movie playback” on 52.6 watt hour battery. Comes with 30w power adapter. MagSafe. Touch ID only. 1080p front face camera.
Base Pro is 8 core CPU 10 core GPU for $1300 USD. 20 hours “movie playback on 58.2 watt hour battery. Comes with the 67w power adapter. Not MagSafe. Touch Bar and Touch ID. 720 front face camera. But active cooling.
So for $100 with the pro, you gain 2 more graphics cores, “2 hours” or 5.6 watt hours of battery”, a 67w charger, active cooling, and Touch Bar (not necessarily a huge selling point).
The advantages of Air over Pro are: Liquid Retina (vs Retina display, whatever the difference is) 13.6" Vs 13.3" screen size. 1080p Vs 720p front camera, MagSafe, and a bad ass midnight color.
Idk…. I have been waiting over a year to upgrade my 2012 MBP 13”. Insane that for how much money they are asking, you only get a base of 8 Gb memory and 256gb ssd. Really with they had included an SD card reader to add expandable storage (was looking at the flush SD cards available on amazon); $200 for a storage upgrade is ridiculously steep. Tough to decide which one to go with now, including 2020 M1 air (which order I just canceled at sale price of $899). As others have stated, I feel that the price scheme is way off.
