Inking on Lenovo X60 Tablet feels way better than on MacMini with bigger Tablet

I've been inking on my MacMini with MangaStudio 3.0 for a few days. It was OK, but somehow I found the workflow sluggish. But this morning I tried using my Lenovo X60 to do inking with MangaStudio 4.0 and it felt so much better. Maybe I should use my MacMini to do drafting, and then do the inking of my tablet PC.
