As a macbook pro user let me say that I will probably not like what Apple shows.
1. I want an m.2 slot for SSDs. They are getting bigger and cheaper and I want the option to upgrade my SSD as they improve.
2. I want memory slots just like my MacBook Pro has. I want the option of adding ram to my notebook like I did with with my MacBook Pro.
3. I want more than one USB ports. A Pro should also have Thunderbolt ports.
4. Keep the audio jack. You do not need to drop it.
