I've used iGoogle as my home page for a few years now, with the usual Google search box but also various "widgets" on there - news links of various types, sport, weather, and so on.
Google are discontinuing iGoogle from tomorrow so I thought I'd better look for an alternative browser homepage. There are lots of options out there and some are really customisable to the nth degree, but I settled on this one as it's intended to a be very similar alternative to iGoogle, almost a straight replacement. As such, it seems to work pretty well. www.ighome.com
