I just won an iPad, any games that are must buys?

My dad just won an iPad from a raffle at work so now my house has one. Since I'm the tech savvy person of the house I'll probably get the most use out of it, that and it's linked to my iTunes account. Anyways I was wondering what games are must buys for the iPad? I'm probably going to buy Plants vs Zombies HD but either than that I don't know much about iPad games and I don't trust the top rated ones. 

That Game Dev Story. 
 
Maybe Puzzle Agent?

I'm a big fan of Canabalt myself. Simple but very stylish and always entertaining. Check out the Flash version online if you want a taste.

That's probably the only way I'd get one.  Our school just got one some how through a grant, seems like a waste of government money.
