Battery life is a bit of a let-down, and the charging time even more so. I'd say that's borderline unacceptable. It really illustrates the fact that they should have just bit the bullet and gone USB-C for charging. They could have gotten normal charging performance, and when they have to inevitably make the change anyhow in the not-too-distant-future it will be one less variation of charging style for a lineup that has already had too many revisions in its short life.
I'd say it's more along the lines of perfectly acceptable. It is pretty much exactly as i expected. USB charging has always been a joke for tablets.
