Actually,it's good to hear the difference isn't that noticable, because LW didn't want to cripple the free version. Instead, Pro searches just get a bit of a boost, and maybe a few other tweaks. . . . and some Pro email support I guess.

re the betas, they may help, since all the changes are designed to help LW work better. If your machine and setup are fairly standard, try a beta a few days after Sam posts the announcement in this forum: somebody will probably have checked it out first for any nasty surprises.
