Many iGoogle alternatives have popped-up on the web over the last eighteen months or so. I was never a big iGoogle user so I didn't miss it when it went away. That said, iChrome is an iGoogle alternative that I can see myself using on a daily basis. iChrome uses and iGoogle-like interface to display your calendar, notes, apps, favorite sites, and more whenever you open a new tab in Chrome. I'm constantly opening new tabs so iChrome is going to put things in front of me all day long.
