Is it possible to utilize Vaadin in a mobile phone application?
To my findings, vaadin apps works fine in iPhone and Android phones. Sure, you’ll need to adjust your UI to make the webapp more usable on a phone small screen, but generally, it works.
It would be nice if there was a mobile/iPhone approved theme that shipped with Vaadin. 
Yeah, generally it works on modern smartphones (iPhones, Nokias etc), but since the components are not specifically made for mobiles, it might not be very usable out-of-the-box. Though with some careful selection of components and theming, one should be able to make a decent app.
(Hint: there is room for a mobile widgetset in the incubator… 
An example of components not working so great: although Table works on the iPhone, you have to scroll using a two-finger-swipe - a gesture not very many are aware about.
Also, the Nokia browser (at least the touch-screen version, as seen on the 5800) does not trigger mousedown/up/click properly, causing problems in some instances.
More gotchas like these almost certainly exist.
