This should probably belong on Endgadge but I'm curious what the Giantbomb community think are the better apps? 
 
Plants vs Zombies runs pretty well on this btw lol

The receipt to get your money back.

ZING! 
 
How about the Sam and Max game?

Sounds like the framerate on Sam & Max is kind of assy.

I got Geometry Wars: Touch. It's not terrific, since it's a much better game when you have proper analog sticks, but at least it looks pretty nice.

I'd say Mirror's Edge, the gameplay itself looks simplistic but it's pretty lengthy for and iPad game and looks nice
 
Tested has a QL up of it

I'm assuming if you're here, you're curious more about games than productivity or other media apps. I think there are far fewer "must-have" games, but in my mind it's really flight-control HD for a fun, quick-play game, you already have PvZ, and Mirror's Edge, so long as the price isn't too much. 
 
There's obviously apps like Pages, Reuters, BBC, Epicurious, IMDB, Pandora, Kindle, Netflix, Shazam, Wikipanion, Npr, and others, most of which are free or 99 cents and are totally needed, but you'd be better served at Endgadget or Gizmodo for those (although you seem aware of that). 
 
Also, be prepared for a lot of iPad bashing since, well, most people here aren't that into tech, or if they are, are discussing it on tech-sites.

Some games that I like for the Ipad are Uno, Scrabble, We Rule(for those who like stuff like Farmville) Espgaluda2(iphone/ipod touch game that works great and looks ok on ipad) and for racing NFS Shift is not bad at all. Other cool apps are Beatwave if you like to make fun music, sketchbook pro and ArtStudio are awesome for drawing and sketching :D
