Discuss recent conferences Google I/O, WWDC, sllconf

There have been several recent conferences of interest to software businesses (u-ISVs). These include, Google I/O discussing Android & Chrome, Apple's WWDC, and sllconf (Startup Lessons Learned).

I'm planning to attend WWDC and can share info on the experience. Would be interesting to here from others who may have attended these or other conferences of interest to software businesses.
