Several organizations in a wide variety of industries globally have begun using Lotus Software on the iPad. Here are some references for your review.
“Lotus Notes Traveler on the iPad is convenient and helps me stay on top of my e-mails. I don’t have to go home at night and fire up my laptop to see my messages,” said Dave Stall, Lotus Notes Manager, Roto-Rooter Services Company. “The iPad is sitting next to me on the couch and I can respond to anything that needs my attention quickly.”
“I like when forwarding an e-mail, you can type the first letter of a person’s name and get a list of people. You then select that person by tapping the screen. This saves a lot of typing and time,” added Stall.
“I can see this taking the place of a laptop for the executive and sales staff, and they live on e-mail. Lotus Notes Traveler makes that transition easy,” said John Roling, IT Director, Czarnowski, an IBM client and business partner.
“When Lotus Notes Traveler iPad users are in a meeting, they can now have up to date ‘push’ mail and calendar,” said Almar Diehl, Groupware Consultant, e-office.
