Then I suspect that you would not fit into the "professional" category as defined by the OP. (That's not to suggest that the OP's definition of the word is the only appropriate one).

So do I but,

1. I carry a Kindle with me. I read a lot and I can do it as well waiting in a office/lounge/Airport as at my bed.

2. I don't value my time more than collective time of four people waiting for me to start a meeting/meetup/lunch.

This reminds me of an idea I had for a product: place value on your and your colleagues time by creating a market for it. The market runs in the calendaring application - you are allocated a certain amount of everyone's time to take for meetings. If you want or need more than your allocation, you have to trade for it. That way you are forced to invite only the people you really need, it quickly becomes obvious whose time is most important, the overall amount of time spent in meetings is limited, and people become cognizant of the "value" of others' time. It could be built as an outlook plugin, even.

no link handy, but a similar thing was tried with email before. You had to offer points for someone to read your mail, and readers would natutally read the highest-paying emails first. The results sounded cool, similar to what you were predicting-- everyone got more conservative with others' email-redaing time. With the email version, you "traded points" by reading (or replying? I forget) your mail.

I'd love to try your calendar version!
