Tricorder (free): turns your screen into a simulated Star Trek tricorder. Has some interesting (if mostly useless) data the phone/GPS pulls up, like gravity info, solar activity, compass... mostly just a 'fun' app.
GPS Status (free): Another gps app that will do a few neat things. Tells GPS location (lat/long), magnetic field at your position, compass, acceleration, velocity, and lets you point your phone to the location of the nearest GPS satellite. This one's more useful that tricorder if you get lost in the woods or something. Also has a 'radar' mode that will let you trace out a path (or something, haven't figured it all out yet).
Google Sky (free): When properly synched with GPS, you can hold this up next to whatever celestial body you're wanting to identify, and it tells you what you're looking at. Where's the moon? You can search for heavenly bodies and it will make an arrow that you can follow to point to where an object is.
Night Clock (free): turns phone into an alarm clock, you can adjust the color/brightness of the display, set a custom alarm tone, snooze duration. Only concern is it might burn the screen if left on all night every night...
Bubble (free): a bubble level app, pretty damn accurate.
Battery Graph (free): to help all of you people boggled by the battery meter quirk, this gives a graphical representation of battery use. I would have returned my Moment if I didn't have this to show that the battery holds at 15% for like 6 hours, so it isn't actually at 15%.
Flashlight (free): Turns screen white, sets backlight to full power. The app description is funny, but its just simply something to give you some light. I wish it would turn on the external LED flash, but whatever.
Shazam (free): "What's this song called?" Ask no more... Identifies a song by listening to part of it. This works even in a crowded bar, unless you're too far from a sound source.
Twidroid (free): Twitter app. Simple. Sounds cool.
Unit Converter (free): Self-explanatory, handy for me (engineering student)
Movies (by Flixter) (free): looks up movie times, reviews, dvd releases, and some other nifty stuff. When GPS is set to active, it will find theaters and rank them by distance from your location.
Advanced Task Killer (free): Kills apps. Go away, random app!
Barcode Scanner and/or Compare Everywhere (both free): Scans barcodes, finds prices/product info. Not totally reliable, but neat.
Mabilo (free): Ringtone app. Works like android market, sort of.
Ringdroid (free): Lets you make custom ringtones from mp3s.
Battery Widget (free): push it and it lets you disable/enable wifi, gps, bluetooth. Also shows a bigger battery meter with %.
Sound Grenade (free): makes that super-annoying mosquito sound. Set it off in a crowd and watch people freak out (hard to pinpoint!)
