Pros remember the shortcuts they constantly use, they don't care what's printed on the keys.
as long as they have keys.
true statement.
like saying: pros don't look to the keyboard while typing: for sure my fingers can find the right key without looking at it, but what if there are no more keys under your fingers?
this remind me the physical key to touch screen transition.
after 3 months i was able to write an entire text message with one hand without looking to my n70 screen using t9 (i even learnt the different alternative words offered by the t9)
after 6 years on an iPhone i can't write 2 words without a typo if i don't look at the screen.
