Further Enhancements Could Take Advantage of Their Host Platforms

• No hardware manufacturing issues• Plenty of processing power / speed

Example 1: Free42 byThomas Okken with significantly more program memory

• Plenty of memory• Easy off-line storage for sharing user-generated data

Example 2: 42S RPN Calc with larger displayfor more stack levels or more program steps

What About Apps on Tablets?

• Larger touch screens could allow for enhanced simulatedkeyboards and screens

• Simplified menu “labyrinths” possible

An “Extended” 50g Tablet Application

• The challenge would be toport calculators to tablet platformsand enhance them to take advantage of the increased“real estate” for bigger screensand keyboards

• Going farther than handheld hardware can go:

• More keys / fewer keystrokes• More soft-keys for user menus• Larger objects displayed• More complex graphics• Better input-forms

• Consider creating new advanced calc apps from scratch for the tablet environment
