I’ve just had a quick look through my app list and here are my most used I think … all of them free:
Air Control Lite - fun game where you draw the flight paths of planes to get them to land on different runways without crashing into each other
Alchemy - irritatingly addictive game - difficult to explain - get it though
Battery Indicator - tells you which apps are using how much juice
Doodle Bowling - bowling game
DroidStats - keeps track of how much data you’ve used/how many texts you’ve sent for your contract allowance
FxCamera - fun effects to play with
Grid Droid - addictive game
Light Racer - Tron game
Paper Toss - you probably had this on your iPhone - still addictive
Robo Defense - strategy game - build towers/kill monsters
Slice It - another addictive game
Urbanspoon - restaurant picker
Wordfeud Free - Scrabble online
did you steal my phone :P+1 for air control lite
Some games
Free
Air Attack HD - If you’re old enough to remember Capcom’s classic 1942 then this a updated 3D like version. Nice.
Speed Forge - Like Wipeout on PlayStation
Paid
Guerilla Bob - Like Crash Bandicoot with guns 
Raging Thunder 2 - Like Sega’s old SCUD Race
Reckless Racing - Remember Super Sprint
Just got my missus a Desire S.
Apps? Jefit and FatSecret well they are my most used anyway. Oh and Notes 
Jefit is awesome if you’re a Gym goer.
DropBox is invaluable for moving files from PC to phone and back, nice and easy. Here’s my affiliate link, would both get 250meg if you use it -
As a US TV show watcher (through torrents) I love TV Show Favs -
For Podcasts, BeyondPod has more features than anything else I’ve seen -
Then this is all run through Launcher Pro Plus. For me, the best launcher out there. Love the 15 scrollable icons (3 screens of 5) along the bottom and scrollable widges (Plus version only) -
