I like it, particularly how partial I (and most others, it seems) am to using the CB for character sheets. There's just so much less to have to deal with on it compared to the previous sheets. Having everything on one side of one sheet makes things easier. I really do hope they add this as an option to the CB. It's a nice option. I'm more concerned with getting power and item cards out of the CB than having all the little numbers available to me on my character sheet, anyway.
I too hope that this will be an option within Character Builder. However, I'll point out that you can customize your character sheet within CB already to get it down to one page if you like. I've been doing that for months, and it's much better for me. Just get rid of boxes that you don't need (most of your basic attack power info, your power list, character portrait, background info, notes, etc.) and get rid of blank lines in other boxes that you do need (feats, equipment, etc.). I've only used it for characters up to about 4th level and I know that it would get impractical at some point as the feats pile up, for instance, but for low-level characters it's fine.
