Let me tell you few points why I dislike sites developed exceptionally on Adobe Flex.
- Non-standard gadgets.
- Blurry text.
- Useless context menu.
- Browser's keyboard shortcuts and extensions don't work.
- I hate "Loading" screen.
My opinion what if one is going to use flash, it should be in small elements around a framework of web standards such as HTML & CSS. Fast, clean, simple and effective.
