How is it playing/looking? Considering picking it up.

If it's like the other updates Gameloft has been pushing out for their other apps then only the icon is updated for retina display. Both Assassin's Creed and Gangstar were updated but only the icons here updated to high quality, not the game itself.
 
Picture Safe (HiDef) -No#1 Privacy App. has updated.
Full support for Retina display (iPhone 4).

Doodle Jump was just updated for Retina display and it looks amazing.

Can't wait for Angry Birds now so I can play through it!

About time, I use this game the most. :) BTW If you like Words with Friends HexaLex is a great take on the game with random online battles too. :D

I was thrilled to see that, too. I play *all the time* and it was kind of disheartening to see how different an optimized app looked from a clearly unoptimized app.
 
Strategery updated in early August but I missed it until now.
• Compatibility with iOS 4 multitasking
• Some improvements for iPhone 4 retina display
 
Epic Citadel

Epic Citadel

It's the tech demo that Epic showed off during the event today, but you can only wander around the town, no real game play. Absolutely worth downloading though (it's free!), pretty mind blowing.
 
OmniFocus, an advanced to do app, uses an iPhone specific feature. You configure your errands with addresses and the app then creates a list view and a geo-tagged multiple pin-drop map showing your best itinerary. The list view tells you your approximate distance from each.
