Keith Barbour cleans the exterior of the not-yet-open Apple store Tuesday at The Gateway in Salt Lake City. Apple Computers has confirmed it will open the store — the company's first in Utah — on Saturday. The grand opening will take place at 10 a.m. at the store, 10 S. Rio Grande. The Apple store will offer all of the company's latest products, including the iPod Nano, as well as the full line of computers. Customers may test the entire line of products and pose their Mac-related questions to staff at the "Genius Bar." The store also will offer workshops and seminars on a variety of subjects. During its first week, workshop topics will include iMovie, iDVD, iLife, iPod and iTunes.
