Microsoft isn’t the only one giving away IDEs. Java Studio Creator is now a free download.
Either Sun wasn’t getting many takers at the normal US$99 price point (which was chosen to accomodate the entry-level developers for whom this tool was designed), or they feel a free IDE will promote the Java platform even better.
No word yet on whether this is a permanent change, so you should probably jump on this offer right away if you don’t want to miss out.
