I like scoremobile, Ubertwitter, NWSclient (render fast) as a weather app, I also like weatherbug, gtalk, Ka-glom, and some of those "link apps" like espn and washingtonpost.

Pretty much, on a daily basis, I use UberTwitter, BeeJive, FourSquare, Ascendo Money, Poynt, KeePass, Opera Mini, and Pandora. I'm also using BerryBlab a lot more now.
