Best Apps?

[Mike5150]

It looks like a huge majority of people are coming from TP2's like myself. Since many of us are new to android, I was hoping someone could start a thread to suggest the best apps. I used Pocket informant as my calendar app, and Phone alarm to switch sound schemes based on location or time of day. These are 2 of my biggest priorities right now, but there are so many apps in the app store it's pretty overwhelming trying to figure out where to start!

Thanks!
