My favorite Android apps--so far

I don't think I'm a typical smart phone user, but (to be honest) I don't know exactly what that description includes.  I enjoy my phone, but it's a challenge for me to use it and still be a participant in any other activity. Either I'm messing with my phone or I'm paying attention to you--it's not going to be both.

Three months down the road and I find myself disappointed (not in my phone, love my phone), I thought my brain would automatically grow new paths/dendrites to accommodate this new activity. I haven't noticed it happening. Is there a study available for that? I might volunteer just out of curiousity.

Back to my original ponderings: I have a short list of favorite apps to share and I'd like to find out what yours are.

• Barcode Scanner
• Flashlight
• GasBuddy
• Google Sky
• Instant Heart Rate Monitor
• Lightsword Lite
• Ringdroid
• Spirit Level Plus
• COL Reminder
• ColorNote
• Klondike
• LucyPhone
• PicasaTool
• Shush!
• Angry Birds (here)
• TuneIn Radio
• Dolphin Browser
• Public Radio Live (Hmm, couldn't find free version)
• Amazon App Store
• Med Minder (I cleared days of week, as I don't want reminders--just a list)

I'm still trying to decide which Twitter App I like the most. I began with Twidroyd, but when Twitter cut off their service it was a shove/nudge to go out and try some others. I gave Seesmic a try and now I'm test driving TweetCaster.
