You shouldn't ask users how the UI should be. You have to listen to there needs.
Then you have to translate this 'democratic' information into a UI design.
When a user wants a drop-down for every department in the hospital you could translate this into "I want to select a department as easy and quickly as possible".
When 90% of your end users are old people who rarely use a computer you have to ask them about there needs. You will collect the 'votes' and may discover you have to drop some functionalities. And maybe a slider UI will be better than a number ticker/spinner control.
All these facts also apply for desktop/latop PC's.
Remove Flash and notice you wont miss it. More and more websites are using HTML there day's. Removing Flash also improves browser speed and stability (just as removing Adobe Reader does).
I did a lot of Flex developing, but I think it's time to move on.
