I just found out via Slashdot that Adobe is giving away Adobe Flash Builder 4 Standard for free to students and unemployed. Obviously this deal is only any good if you are a software developer planning to use Flash.
We provide free copies of Adobe Flash Builder 4 Standard to:
* Students, faculty and staff of eligible educational institutions
* Software developers who are affected by the current economic condition and are currently unemployed
* Event attendees who receive a special promotional code at their event
