If rumors are to be believed, the next macbook generation is going to get a new body design and new screen, so will be 1st gen in a different, probably more severe sense. Makes it difficult to decide whether to just buy now.
My dream laptop would be an iPad Pro 12.9 with a Magic Keyboard and M1 chip which could run both full screen iOS apps and full Mac OSX. In a perfect world it would have an extra USB-C port too.
But to be honest, just a regular macbook with a touchscreen would be great now. I've had enough of people trying to use my Macbook at work, prodding the screen to try and scroll down, then trying and failing to do the two finger scroll gesture on the touchpad.
