3 apps that haven't been mentioned yet but I couldn't rate highly enough: Pubtran - if you're in London, is fantastic for trains and tubes. Vignette - Absolutely beautiful and beautifully made camera app (lots of filters and whatnot). gStrings - Brilliant guitar tuner. Also worth noting: Pure calendar, Tweetdeck, Google Goggles.
