I agree. Making a lightbulb the way Thomas Edison did is "obvious today". It wasn't the day before he invented it, but it became "obvious" the next day. Does that mean he didn't deserved patent protection? Because suddenly, after they have seen his invention, they slapped their foreheads and said "of course!" ?
That's how it works with pretty much every invention under the sun!
Don't believe me? Try inventing something truly original! Something the world has never seen the likes of before. Try coming up with next year's hot got-to-have gadget.
... Or simply make a new mobile phone so unique and fresh, that it suddenly turns the mobile phone industry (Apple included) completely on its head! Go ahead. It's a free country. Heck, most of this WORLD is free. So stop complaining, and start showing us all how "easy" it is inventing "a rounded rectangle"...
