Wells Fargo & Co. spent two years studying the iPhone before letting bankers use the device at work. Apple Inc.’s iPad, released in April, took just weeks to get cleared.

This time around, safeguards against security breaches are stronger from the start, according to Megan Minich, a senior vice president at the San Francisco-based bank. Her colleagues used two of the first shipment of 15 iPads to demonstrate financial products at an investors’ conference in May. More are on the way, Minich said.

Are you an Apple bull looking for even more ammunition to bolster your faith in the company? Barclays Capital has you covered. In a report today the research shop predicts that:

• Tablets computers, a category that didn’t really exist until this spring, will be here to stay;
• Apple (AAPL) is going to own most of that market for years to come;
• This is yet more bad news for Microsoft (MSFT) and its Windows franchise, as well as PC manufacturers like Dell, in particular.

1. Make sure the iPad is the right tool for the job

Make sure where, and what you’re presenting, is ideal for the iPad. Remember, you won’t be able to use a remote, or have any sort of presenters view. So, if you’re giving a talk in a small conference room where you’ll be sitting at a table with the iPad hooked up to the projector, that’s a perfect use of the tool. Giving a Steve Jobs-style presentation in front of 5,000 people and a large stage? Not so good. In a lecture-style room with a table in a convenient place to allow me to walk around and tap the screen, so I might use the iPad there.
