Well, if your expectation is to just turn the iPad into a laptop, it's not going to work out. If you want to turn it into an iPad you can type faster on, it will be much better.
That's not the middle ground iPad is aiming for, though. It's a spectrum, and it sounds like you'd rather have a Surface. Sometimes I think I'd like one to doodle with, too. I've seen people be productive with iPads as well, but you have to use them differently.
