I was in Reading UK last week to attend the NSConference 2010. I will not write a full report of what happened there, because others will do that better.
The only thing I want to say is:if you want to improve your skills in Cocoa, for Mac, iPhone or iPad, you should go: you’ll have the best speakers, the best organization you can dream of. And you will come back with new contacts, new ideas, new code to try.
You can (should) read Alex Repty report here.
