I love Xcode 4, but one MAJOR pain I hate about Xcode itself is updating it. Apple, please use a patcher to update Xcode. Having to download a 4GB + file every time a new version of Xcode is release is getting old, and ridiculous. Not to mention, 4GB's in one download may look suspicious to my ISP. I won't update my Xocde until this issue is resolved. Thanks. I just submitted this to Apple, hopefully Apple will listen. (removing if any, confidential info) I'll post back any replies.
