1. Mobile Devices

2. Definitions Smartphones are phone first, enhanced to do things formerly reserved for PCs Tablets embody those enhanced computing features in an expanded format and screen Age of the book: Differences between mobile and PC due to interface(s)

3. Touch Interface To start a app, touch/tap the icon Swipe is to move your finger right-left or up- down Holding a finger on an open app brings up context menu Two fingers to expand or shrink an image Multitouch is using two or more fingers

4. Screen Technology Capacitive touchscreens use electrical current in your body to determine movement They measure the difference between the charge in your body and the static charge on the screen Dont require (re)calibration iPad uses In-Plane Switching (IPS) – richer colors and better viewing angles

5. Phones Smaller devices can use organic light-emitting diodes (OLED) displays Apply an electric current and the organic layer glows in the precise spot desired Black and white pattern only lights the white Dont use backlights Lighter and less electricity than LCDs

6. Orientation Rectangular screen can rotate so up is always up (except for the Zippo app where the flame bends and the lighter stays put on the screen) Use accelerometer to sense orientation

7. Operating Systems iOS from Apple, drives iPhone, iPad and iPod touch Google Android runs most others Very small Windows 7/8 presence

8. Apps Enables accomplishment of a specific task Apps not cross-platform (i.e. iOS to Android) While you can port apps from iPhone to iPad, its better to tune them Apple does not support Adobe Flash on mobiles – some web sites wont work Mobiles come with a base set of apps

9. Gotchas Can only get Apple iOS apps from App Store which is controlled by Apple (no porn) Android is tuned for different manufacturers which starts to look like UNIX CompTIA mentions Touch Flow as if it were a standard feature. Its not and its outdated. HTC used it

10. Enhancing Hardware No can do – closed systems No field replaceable parts (FRUs); something breaks you send whole unit back You can plug in earbuds or speakers

11. Apple Expansion Not much even though they dominate the markets Can mirror the screen to a projector (using Apple Keynote)

12. Android MicroSD slots for adding storage Some offer bigger slots Some even offer USB ports Attachment for projector (mini-HDMI)

13. General Wireless (Bluetooth) for keyboards, mice (not Apple) and headphones My iMAC keyboard can synch to iPad

14. Config - networks Settings app Same as a portable computer wireless setup Will need WPA or WPA2 logon information Watch data plan(s) and watch roaming (charges) especially if you go out of country

15. Config - Bluetooth Settings app, again Turn on Bluetooth on mobile device Power on the Bluetooth device Follow on-screen directions

16. Config - email Settings app Tap Add Account for list of popular ones; choose Other for POP3 or IMAP account Android assumes gmail account; offers an Email icon for setting other accounts

17. Config - Sync Apple is simple with iCloud and Mountain Lion Android devices are like flash drives, can share with any PC

18. Preventing Damage Buy cover(s) or sleeve(s) Dont set heavy books on tablet Dont get them anywhere near liquids Android devices support several anti-virus apps Apple does not have an anti-virus solution – thanks to App Store

19. Dealing with Loss Set a strong passcode lock required at startup Most will lock device after failed attempts Find your device when it attaches to Internet iCloud for Apple down to a few yards; Google a little more Called Locator Services

20. Recovering from theft Apple is easy: Remote Wipe if you can find it with Locator Services Android also
