I recently discovered MoneyCenter.yodlee.com.

For tracking account balances, upcoming bills, etc, it works just as well for me as Microsoft Money did, except that Yodlee supports more services.

It has account notification emails for all kinds of conditions (bill due, transaction exceeding $x, etc). It has transaction categorization, report generation, budgeting.

In some respects it's better than Money, in others the web interface limits it. The most useful aspect of it (to me) is I can use it from any web-accessible system. Linux, Windows, Mac, etc.

I was initially wary of putting all my banking information into a website, some random web service that somebody put together. Then I remembered a little disclaimer in Microsoft Money that some services were provided by Yodlee. So now I'm skipping the middleman, and don't have to trust Microsoft to transmit it securely.

edit: Crap, I sound like spam. Edited to sound less... spammy.
