Tough call right now as I'm leaning against moving to 4E.
If I do, I could see myself doing it. Frankly, Dungeon and Dragon magazines stopped at the right time for me because I'm out of bookshelf space for it. I literally have two full shelves in a large book case devoted to articles that I usually read once and then forget about. Dungeon adventures can be easily printed out, but I fail to see the point in doing the same for Dragon unless it's a very useful article. Having less important periodicals archived in PDF format is great because it saves me space. I also like the format of issue 360 (if only they could get the sidebar to alternate pages like it's supposed to in printed format, I'd be very happy). Also, as someone who has the full version of Acrobat, I can chop up the PDF documents and recombine them so I can make my own personal, not to be shared, "Best of" compilations.
I also see value in the electronic game table and would be likely to take advantage of it.
So right now a lot for me comes down to whether or not I think 4E is a dud. I'm very much on the fence right now. There's a lot I've read that I don't like, but there are a few things that sounds somewhat promising. I guess what will really do it for me is to see what changes they make to the combat system, since that's where so much of the streamlining of the system is really needed.
