I read the following in the winter 14 release notes for the Force.com IDE:
https://wiki.developerforce.com/page/Force.com_IDE_Release_Notes#Supported_Platforms
"Eclipse Platform Version 4.2 "Juno" Note: The Winter ’14 release no longer supports Eclipse version 3.x. If you rely on Eclipse 3.x, you can use an older version of the Force.com IDE, but older versions will not be updated with the latest metadata enhancements."
I'm currently using Eclipse 3.7 on Windows 7(64bit). I'm the only developer in my organization using Eclipse at present. It looks like I could leave my Eclipse setup as is if I don't need any new features.
Have you experienced any major advantages/disadvantages from upgrading to 4.2(and the new metadata updates)?
edited I have accepted an answer, but I'm interested in feedback and will vote up additional good responses that appear here.
