Highlights for me:
 
 White Lies @ Empty Bottle - great club, great sound and cheap beer - and my new favorite band! Awesome set. Meeting White Lies was just awesome. Talked to the guys for a bit and they were the nicest of people.
 
 Radiohead - fake plastic trees/everything in its right place with fireworks (near having an emotional breakdown)
 
 Electric Touch 
 CSS
 Booka Shade
 K'naan
 Innerparty System
 Mark Ronson & Phantom Planet played "California"
 Chromeo
 Nine Inch Nails
 Explosions in the Sky
 Foals
 Holy Fuck
 Perry Farrell (on kidzapalooza stage)
 The National (only caught 3 songs - was amazing!)
 Office (mostly heard them from the signing tent, but really liked what I heard)
 
 On-The-Fence
 Broken Social Scene (nice to see Amy Millan)
 Love & Rockets (started out great, but I left a bit disappointed)
 The Kills (such a short set! - turns out the heat ended their set early)
 Kanye
 The Enemy UK (theyll be awesome in a club)
 Your Vegas
 Okkervil River
 Does It Offend You, Yeah? (were awesome by the middle/end of it)
 Rogue Wave
 Brazilian Girls
 
 Who I will never see again:
 Iron & Wine (i slept through most of that set - it was god-awful, boring, sleep inducing)
 Black Kids
 Louis XIV
 Manchester Orchestra
 
 Other things I liked:
 food/drink prices
 mango/strawberry banana smoothie 
 polite/friendly airport security
 Zipcar
 driving around Chicago
 Wicker Park/Ukranian Village
 Silversmith Hotel
 The nice people I met at the festival
 
 Things I detested:
 Newark Airport/UAL - I will NEVER fly them again and I hate Newark Airport.
 
 Weather delays going in and out of Chicago
 
 the mean people who felt the need to shove me so hard that i now have bruises all over me (and no this wasnt for Rage Against The Machine - it was at Broken Social Scene and Your Vegas)
 
 Not enough bathrooms/insanely long lines for them
 
 The _long_ wait to get into the festival causing me to miss some of K'naan's set
