Useful: AttnGrab solves the main problem I've experienced with Palm Treo and Centro phones: the lack of any nagging notification system when you miss a call or alarm.
If I ever live in New York, it'll have to be within walking distance from Mikey's Hook Up. It's a music store crossed with an Apple dealer, with a big ping pong table in the middle.
Fun: In case you ever need it, there's a web page that flips text upside down for you.
Tasty: Spiritual Groove is new age guitar and violin, and sounds kinda like a Al di Meola and Jean-Luc Ponty duet (which is a good thing). Also, Stu Hamm plays his solo bass tune "Flow My Tears" (the recording is from an old instructional video).
Funny: The Streetly Electronics Mellotron Tape Library 2008 (read the descriptions), Metasonix's TM-7 distortion pedal, Penny Arcade nails it with Le Twittre, and Garfield Minus Garfield is better than Garfield.
Bittersweet: The Dogs - You Mama´s On Crack Rock. Sorta kinda funny, sorta sad. Especially sad if this is true: (from http://en.wikipedia.org/wiki/The_dogs) "made the song from a real life experience with his own mother's addiction to crack cocaine". The opening verse is about said mama prostituting herself for crack. A song calling his own mom a crack whore... Grammy material, I tell ya.
