The convertible tablet space is a tricky one. After several years, no one’s managed to precisely nail it — no device will ever manage to straddle the line as the perfect laptop and tablet. But the category is a rare bright spot in an otherwise stagnant tablet market, and Samsung’s never been one to stand down from a challenge.

If nothing else, the Tab S4 represents Samsung’s most aggressive approach to the category yet. The company appears fairly confident that it will fulfill the need for both laptop and tablet for a certain segment of the population, at least — which would go a ways toward justifying that $650 starting price.
