Jeff,
I too had issues finding reviews but I did go ahead and install it on a client's system. The results were great, espcially the USB re-direct. I have it installed on a HP and a Dell. I do like the performance better on the Dell but I also think thats because the users are more experienced. So it may not be a hardware issue as much as a user issue.
I am using both the lite and professional version.
Good luck and I hope you enjoy it as much. I will warn you that the documentation is light but the email them with any questions and they are great at helping out.
Cory
