Is it realistic to try and learn and code a Flex 3 application without purchasing FlexBuilder? Since the SDK and BlazeDS are open source, it seems technically possible to develop without Flex Builder, but how realistic is it.
I would like to test out Flex but don't want to get into a situation where I am dependent on the purchase of FlexBuilder (at least not until I am confident and competent enough with the technology to recommend purchase to my employer).
I am experimenting right now, so I'm taking a long time and the trial license on my Windows machine has expired. Also Linux is my primary development platform and there is only an alpha available for Linux.
Most of the documentation I've found seem to use Flex Builder.
Maybe I should use Laszlo...
