Expanded the list a bit...

Anti-virus - housecall.trendmicro.com -
Media
Radio style Music - pandora.com -
On-demand Music - imeem.com - This is nowhere near as user-friendly as Pandora, but you get to hear the song you want to hear right now
Photo storage - flickr.com - I actually use Facebook. Both Flickr and Facebook are directly linked to Picnik.com, a third-party, web-based app that lets you do simple fixes like cropping, rotating, and brightness/contrast.
Serious photo edits [1of2] - pixlr.com - This does 90% of what Photoshop can do, which is pretty incredible for something web-based.
Serious photo edits [2of2] - sumopaint.com - Does 90% of what Pixlr.com can do, but can also feather a selection
Video storage - youtube.com - You can upload straight from a memory card or e-mail a video in from your mobile phone. You can even record straight from a webcam, which means that you never have to take up memory on any local drive. You can mark videos private, which you can then share with up to 25 people
Colored noise generator - simplynoise.com - I prefer oscillating pink
Audio editor - aviary.com/launch/myna[/L] - Upload wav, aif, mp3, wma, m4a, or ogg. Mix, apply the most commonly used effects and fades. Download as mp3 or wav. Limitations are that registration is required, it's limited to 10 inputs, and the maximum length of sound file is five minutes
Video editor - ??? -
Productivity
Office Suite - docs.google.com - Besides being able to save in the corresponding Microsoft compatible format, you can also save as PDF. I made this spreadsheet in Google Docs.
Calendar - calendar.google.com -
RSS reader - reader.google.com -
PDF Creator - docs.google.com - Google Docs offers the option of exporting (downloading) a file as a PDF
