Editor's Notes
- #3: Ask questions, butAround all day
- #4: How much will be relevant
- #8: Pride in craftsmanshipAttention to detailEngineer the experience to feel polished at every stageBe fast and fluidImmersive and responsiveUse motion to bring life and continuityAuthentically digitalTake advantage of the digital mediumInfographic not iconographicRealism, skeuoporphs and verisimilitudeDo more with lessPurposeful experienceContent, not chromeFierce reduction of UI elementsWin as oneNative integrationAcross form factors and experiencesStructure to aid creativity, not inhibit it
- #12: Because we can do principles without language
- #13: You can be visually stunning
- #14: Can adjust to the conventions of the platform
- #15: Can still reflect brand identity
- #16: iOS – Pure Android – iOS7Your app on Windows Phone won’t be compared visually with how it look on other platforms
- #18: Reviews last
- #20: Summary overview, encourage exploration, like a magazine cover
- #21: Not exactly like a tab control.Intended to show related items or differing views of the same data – e.g. emailNot for wizard type interface
- #22: Lots of optionsDefinitely value for money to be hadToolkit & Telerik
- #23: RadControls essentially freeLarge range of other Open Source controls available too: GeekChamp, GitHub, Codeplex
- #29: State machine3 lines of code is actually 60
- #31: ReSharper – CodeRush - JustCode
- #34: Aids testability
- #35: Is code behind bad
- #38: Suspend and resumeFAS & FAR
- #39: http://www.fanpop.com/clubs/nintendo/images/26503062/Agents – periodic & intensiveDownloading

- #42: don't break the back stack - be predictable
- #43: don't break the back stack - be predictable
- #44: exceptions- end of flow- long navigation- poss. deep link. Toast, not tile?
- #45: exceptions- end of flow- long navigation- poss. deep link. Toast, not tile?
- #49: 190+ countries & 50 languagesLocalization can be an easier way to reach more users than porting to another platform
- #52: Still 10 million devices out there. Only just moved to less than 50% of WP devicesVery easy to support both, especially if not using functionality specific to 87 apps run unmodified + some functionality available via reflection
- #53: IDC estimates 30M WP devices by Christmas, but 200M Windows8 installsCan share code, even the same libraries as there are commonalities to the APIs of bothDon’t share the same UI though.
