To “pale (pale) in comparison to,” or “in comparison with” something means to be less important than something else, or is of less value than something else.

The amount of money you would spend to rent a car for one day pales in comparison with the cost of buying a new car and driving it only one day.

The two things are not equal; one is greater, or more important, than the other.

In this case, Hannah is saying that design and color are much less important than affordability and ease of use.

“Ease (ease) of use” means how easy or difficult it is to use something - to use, in this case, Vision Corporation's product.

For example, most companies try to design their website so they have good ease of use, meaning it is easy for people to find the things they're interested in.

Hannah says that she doesn't have time to address Chris's concern fully, but that most customers aren't interested in design.

To “address” something, here, means to manage, to handle, to answer, or to deal with something.

You might address the problem of not having enough money by getting a second job.

When Hannah says that she doesn't have time to address Chris's concern fully, she means that she doesn't have enough time to completely answer Chris's questions and worries right now in the meeting.

Next Alex begins to speak and says, “If I may offer my opinion, I believe Mr. Hanson has a legitimate concern.”

To “offer one's opinion” means to say what you think about something.

You can offer your opinion about an idea or a project, for example.

Alex's opinion is that Mr. Hanson has a legitimate concern.
