international keyboard layouts, are basically like qwerty, sucks donkey ass. in many cases worse than qwerty for english with respect to ergonomics or efficiency of input. Including, Chinese Input Methods and Japanese Input Method

added lots photos. The integrated touch screen + pen, is truly critical. Beats Apple's. With iPad + iOS, you can't do serious coding on it, and everything you do is sent to FBI, and nothing you could control, even if you are a tech head. But MacBook + macOS doesn't support pen computing, even if you use a drawing tablet. Apple wants you to buy its Magic Trackpad or iPad.

yeah, get it. my complaint is that, watch out if your hand is not big. and, be careful how you use the thumb keys. try move whole hand instead of twitching thumbs. and, i wish it had full sized function keys.

the empty area in middle, put in a programable keypad.
