Here’s a summary of the tips we’d like to pass on; we’ll look at each one in more detail below.
1. Tackle expensive computations when they can improve the interface.
2. Eliminate dialogs and command lines in favor of direct manipulation.
3. Drop old assumptions and idioms. Use the processing power to explore new interfaces.
4. Provide a starting point for exploration.
5. Avoid programming cleverness. Instead, assume a good compiler and write readable code.
6. Invest development time in user-centered design.
7. Learn the new rules for performance.
8. Design tiered functionality: take advantage of whatever hardware you’re running on.
9. Test on real users.
