What is the practicality of using PhoneGap?
I am currently doing some research in using PhoneGap instead of write different code for all platforms. In my mind, right off the bat, one con to this is, in fact, you aren't writing your applications natively. I ask myself, what does this mean? 

1. Will there be a performance hit? 
2. Does PhoneGap offer wrappers for all native functionality? Is the documentation enough to get by? 
3. What kind of UI's would you want or need(i.e. JQuery) and do they have proper documentation? Do these frameworks work seamlessly across different platforms? 
4. Since Adobe is now in the mix will PhoneGap eventually become obsolete and in the long term it just doesn't really matter? 

I would like to hear any feedback/advice/suggestions for those that have tried PhoneGap. Also if there is a list of functionality PhoneGap doesn't provide could someone provide a link? 

Thanks!
