Being even more pedant I will point out that the improvement is a lore more. What is important here is the error rate.

Simply speaking, they went from 4.82 to 4.58 so the improvement is (4.82-4.58)/4.82 = 0.0497 ~= 5%

Another way to see that is that Google made 48200 errors on the full set of 1 Million images while Baidus made only 45800 errors.

You wll never be happy because laptops will never be as powerful as desktops. Simply speaking, if you manage to create a laptop as powerful as a desktop then you can also create a more powerful desktop. That is not a matter of computing power but of temperature. Desktop are by definition bigger than laptops so they can dissipate more heat.

3, 33 or 333 millions. Would that make any difference? I don't think so.
It you want to calculate the expected gain then you should only consider the useful gain.
For me, 1 or 2 millions would be enough for the rest of my life so if I had to choose a lottery, I would pick one that maximize the probability to gain that amount. Any lottery with a smaller maximal gain (e.g. a few millions) but a higher probability is a better choice.
