Here are some of my favorite sites/apps for the iPod Touch/iPhone.
hsicon - Allows you to create your own icons for use on the Home screen. This is most handy for sites not built specifically for the iPod Touch or iPhone. You provide the image, url, and select a background color and hsicon creates the homescreen image for you. It's pretty slick. I'll post pictures of some of my own creations later.
Gno - A quirky web-based game that makes you rely on your connection to the internet to find answers to questions/clues.
iSudoku - A web-based version of the popular Sudoku. Amy loves this, which is the primary reason it's on the Touch.
Solitaire - Your standard game of solitaire. It works fairly well with the multitouch interface, though the landscape view doesn't provide much more screen real estate, which is dissapointing.
I of course have a link to my
Google Calendar and their other mobile apps. I wish you could sync your Google Calendar to the Touch, just as you can one from Outlook. Here's hoping someone provides this in June (Are you listening Google?). I have a link to
LinkedIn via their mobile access which is really handy. Of course I have a link to PGL, an infamous HT website, Wikipedia Mobile, The Weather Channel widget, an aggregator of local gas prices (sad, huh?), and Woot!, just for the hell of it.
I also have a link to Yahoo! Mobile, though I don't use it much since the Touch already aggregates my Yahoo mail.
