here and here. I have owned a Xoom. I was as close to an Android Fanboy as they come. I HATED the iPad and made fun of it for a year, knowing in the back of my mind that I was missing out on something pretty special. I waited, read rumors, did my research, jumped for joy at the announcement of Honeycomb and the Xoom, pre-ordered it, got it on launch day and SOLD it 3 weeks later. It has potential BUT it is not ready.
Are you asking are there things from Xoom/Android that would be wonderful if properly integrated into the iPad? YES! The perfect product would be if the iPad and Xoom had a baby. The "theoretical" SD slot would be nice, the ability to manage files more easily would be wonderful, widgets are AMAZING but the ability to have apps and media developed for your platform all the while running without and millions of bugs and force closes you deal with everyday in the OS would be nice.
