I absolutely agree with the OP.. My first and only Apple device has been an iPad2, and I have never understood why I need to 'swipe to unlock' when someone with a smart cover can just open the flap.
It makes not sense.. I am not saying they should remove it, but there should be an option to disable it.
For people like me who use it to look at something and then lay it down next to them until I want to use it again (which is usually a matter of seconds to minutes later) it becomes really tedious after a while and I am getting bored of it.
I just want to be able to press the home or power button and have my iPad wake up... There just doens't seem to be any need for the "swipe to unlock" action!
