Subject Re: Are we "nerd" driven or "business realistic" driven?
Date Thu, 27 Jun 2013 21:43:46 GMT

I just want to throw in that I have been doing a bunch of apps with Flex
mobile and am constantly amazed at how good it performs across devices.  I
am talking about data intensive visualizations with a lot of number
crunching, charts and animations.

Of course, as with Objective-C or Java, you need to be very careful about
orchestrating your code so that it does not choke the system.

And I have been testing the apps on my Galaxy Tab and iPad, and all real
issues I have been facing is related to dpi mismatches and such.

So, when folks are saying that Flex does not perform well on mobile, can
you please post some examples, etc so we can try to figure out what the
real problems?  As opposed to sweeping statements like Flex mobile sucks,
