am sitting on the sofa all day (not typical, really), running on the battery... and still 50% left.
am loving this thing. working in: affinity photo, dreamweaver. music playing (earbuds). safari's open (about 16 sites), checking email, messages; making notes, some calendar entries. and not for a moment does anything feel sluggish.
crashplan running in the background, so everything's backed up.
really, my fave mac to date (and i started with the then amazing 2400C (google it)). a great time for apple, really...
