Google has finally heard my prayers and responded with a calendar app in the same style as Gmail.  It's still pretty early in its maturity, but it's got all the basics covered, including Gmail integration and a nice web invitation feature.  Between this and Gmail, it's safe to say that my home/personal PIM environment (as opposed to work) is no longer hindered by a lack of Outlook .  Besides, for personal data, I prefer the web-based stuff anyway, since it's way more portable.  Leave the work stuff at work, but I want to be able to get to my personal stuff anywhere.

Some things I'd like to see:

1. A to-do list with reminder capability.
2. A desktop reminder agent (integration with Gmail Notifier, perhaps?)
3. Configurable notification addresses, so I could use email addresses outside of my Gmail account (although they DO provide SMS capability - that's a plus!)
   

Now I've only got one app that I'm still dependant on my PC for, and that's Quicken.  Intuit has a web-based entry tool, but it's lame, and it doesn't even work with my Quicken.com account because of some silly issue with my Quicken.com account being permanantly associated with a Quicken file I don't have anymore.  In other words, it sucks.  Bad.  If either Intuit or Microsoft would come up with a decent online PFM, complete with billpay management via OFX, I'd pay good money for it.
