Things to think about

Don’t port your desktop app Reimagine it

Reimagine

The app represents more than your device Use it well and use it wisely

The app represents your company

Participate fully in Windows 8 Think about how your app and device can be of value to others 1+1=3

It’s a Windows Store App

Anyone can discover and download your app Give them a good experience

Discovery via the Windows Store

Should do something useful with the device Not just an advertising surface

The app must have some value

You can have in-app purchases Opportunity to offer latest model, accessories We don’t take a percentage

Device apps must be free

Your device must pass Sysdev certification Start learning about this early

Your device must be certified

You can target your custom drivers to work on these two platforms Work with OEMs to develop on ARM devices

Custom drivers work on x86/x64
