Apple didn't have the first tablet. Microsoft has been trying for decades
Those pre-ipad tablets with their styluses are about as ancient as an apple newton. That's not a fair comparison.
Apple was the first company to get tablets noticed by general consumers,
That's because it had a great design, unlike its predecessors.
The Surface Pro was an incremental step from the many different types of convertable laptops.
Wrong. The surface pro is MS playing its usual game of cloning a market leader (embrace), in this case the iPad, and adding features to it (extend), i.e. a keyboard.
