Have had my Xoom for about 5 days. One question... How in the heck do you "close" an app? For example, I will open a browser and surf a bit, but I want to go to a game and play. Today I simply hit the home icon and go to the game. But doesn't that keep ther browser open? Also, then after the game I will check my e-mail, etc. Just seems that I keep opening these apps, but never really closing them. I look around occasionally to see if I'm missing some magic "x", to close it, but never see one. Any ideas?
