What are they talking about?

M: Have you gotten used to the new software John installed on your computer yet?(56, 57)It’s supposed to be faster and easier to use than the program that was originally there.
W: I don’t know because I haven’t had the time to use it yet. (57)I’ve been away on a business trip and just got back this morning. Tell you what, I will try it out this morning and let you know how it is at lunch.(58)I just hope it won’t take long for me to learn how to use the program.
M: You shouldn’t have any problems with it. The command keys are exactly the same as the old program.
W: Is that right? I guess I won’t have any problems using it then.
