I’ve been using VDJPro7 on my net book for nearly a year now and I really enjoy it. I run two decks and have mapped my keyboard.
My cons:
1) I think VDJPro7 is meant to run on something more than a 1.6GHz Atom processor, so many of my skipping/lagging issues stem from this
2) The effects (in particular echo) seems a bit tinny (if this makes sense). Again, this could all be due to my tiny processor.
