E-Magazines?

I just re-upped my subscription to a magazine I enjoy, when the thought occurred to me...

How long will it be before all mags go to e-version?  Or will they?

Will they be available only online, and I get a notification that the newest issue is there for me to read?  Will I get to download a copy to my e-reader?  Or will my issue be sent to me via email as an attached file?

Worse, what's going to happen to all those perfume samples that made my mailbox smell so good?
