Flex/Flash is vector-based UI, when all assets are expressed in the form of vector, the UI can easily go resolution-independent, that means your app would look just as sharp on 72-dpi old monitor, to 120/150-dpi modern monitor all the way to retina display on iPhone 4 and above.
With image/bitmap-based approach, if you supply multiple version of images catering each resolution, you will have optimal display quality but it increases the burden of image preparation. This is not issue of Flex or Flash, it is any bitmap-based approach will have this problem, notably HTML/HTML 5. If you opt for not supplying multiple versions of images, you will then force the app to resize an image, which is generally an expensive operation especially if you turn on interpolation for better display quality. With the shortcoming of Photoshop-base UI mockup, lately I have been switching over to Adobe Illustrator for UI design, it is painful at first but the investment is well worth for the outcome.

I have been working on iPad apps by just skinning the components. But sometimes there are some UI designs which are difficult to achieve by skinning. Hence wanted to know if we can extensively use images to build an app in flex. Something like these: http://dribbble.com/shots/172145-Mobile-admin-dashboard-iPad-UI-UX-iOS http://dribbble.com/shots/722800-Experiment-with-Metro-UI/attachments/68300 Kindly let me know what can be the best approach. Cheers, Deepak
