iGoogle is ending next November 1, 2013 and the mobile version already ended this past July. According to Google, the decision is based on the use of modern apps created after iGoogle came on the scene in 2005. Apps that run on Google platforms like Chrome and Android (to name a few) have made the widgetized iGoogle, well… irrelevant, so after November 1, 2013 iGoogle will come to an end. So you have 16 months to transition to other platforms.
If you want to move your personal data from iGoogle you can export it and use other Google products including Gmail, Google Calendar, Google Finance, Google Docs (now Google Drive), Google Bookmarks, and Google Tasks. As an alternative, Google is encouraging iGoogle lovers to use Google Chrome. The Chrome Web Store provides a similar range of options once available on iGoogle such as productivity tools and applications to check the weather. In addition, just like iGoogle, you can personalize Chrome with a theme.
