I think since they are going to nickle and dime you for the online version of the content they'll make keeping it all up to date is a priority.

It's the nickle and diming that would keep me from playing with the OL tools - My husband and I play so I gaurantee we'd both need accounts to play together rather than one household with two accesses usable at the same time. Plus another computer etc..
all racked up it's not worth it just to play LD with other people. Cheaper to drive and\or host a couple times a month

Have they announced pricing? We just lost one of our players who moved to Philly (we're in RI) and would love to have a tool like this.

Honestly, I don't see the point in printing books for D&D. I'd rather have an online account (if its a reasonable price, like $5-10 a month) and a well done, easy to use reference site where I could print out the few charts I might need and just have everything else on the computer.

For me, I hate computer docs (PDFs) for my initial read through of any RPG content. However, for anything after that (reviewing lore, looking up rules, etc) I prefer a nice bookmarked PDF.

I've even taken to buying the physical book and then purchasing a PDF of it on RPG Now if I actually want to use it.

Well, there are many people who are reading 4E previews are saying that it reads like an MMO at the moment (guys from Green Ronin are the only ones I have heard from, but they proxy other statements), so it shouldn't be too much of a problem for them to do it, but seeing that 4E is being a titch bit rushed as well, it makes tough to iron out the differences between POTENTIAL and ACTUAL results...
