Long winded search
"On a non-Update 1 system, searching meant you had to swipe your finger in from the right edge of the screen to start the process, or hover your mouse over the lower-right hand corner of the screen and then move the cursor up to the Search box to type in your query."
Yeah, or you could just press Start on your keyboard and immediately start typing what you're searching for! Why faff around hovering over things with your mouse etc, especially on a system with a keyboard?
I'll admit it's nice to have an actual search box on the Start screen, but purely because the idea of just typing without putting the cursor somewhere does blow some users minds.
