Soon after the EVO 3D was released, I wrote the above post with some of my recommended apps. I still stand by it, though I've stopped using the widget from Foxyring I mentioned, and am now using the "timed silence" widget from Beautiful Widgets instead.
Here are a few other apps I've "discovered" since then, but am enjoying:
If you like architecture or just find unusual buildings interesting, "Buildings" by OpenBuildings, Inc. will interest you. if you like buildings and are a history buff, you will especially love HistoryPin, which links to old photos of buildings in your area (or in another area you designate), gives you GPS directions to the photo site, and encourages you to take a current day photo through a unique camera viewfinder that lets you overlay a "ghost" image of the old photo over your viewfinder.
I got the app "Business Calendar" by Appgenix when it was app of the day in the Amazon appstore, and I find I prefer it to the stock Android Calendar app, and the other calendars I've tried. It's available in the regular Android Market if you don't want to mess with Amazon.
For people who clog up their smartphone with to do items, appointments, and missed phone calls or texts (I'm one of those people), I find the "Executive Assistant" widget by Appventive to be really helpful. Highly customizable, it puts a lot of info about alerts, tasks, etc. in a compact and readable widget.
I find CamScanner to be much superior to the camera app as a way to record documents (including to export them to Evernote if necessary).
I bought Copilot Live Premium USA (a navigation program that installs the maps on your SD card so you don't need a 3G connection) to be very useful the one or two times I've actually needed it. If you never drive out in the country, you may not care about this. But I like having it as insurance. It works well, and the maps are very good (not perfect). I bought it for ten bucks during an introductory promotion, I understand it is more expensive now, they claimed the regular price would be thirty dollars. The older version of what appears to be the same software (without some interface improvements and other upgrades) still looks to be available in the market for ten dollars, and may be a better buy.
During a Federal Emergency Management Agency press conference on the storm, I saw mention of a FEMA app for Android and iPhone. I've downloaded it, but haven't used it yet. It apparently has good information on initial response to emergencies available so it will be on your phone even if the network or power has gone out. It's free, so you may want to get it. Be sure to get the Android market app from FEMA, I know nothing of a similarly named app in the Market by some other organization.
I just finished my first trip (to Virginia, where I was there for the earthquake, and flew out early to get away from the hurricane!) using the Tripit app to keep track of all my reservations, and it works well. It is very convenient that it strips reservation information out of your confirmation emails without your intervention, and puts it all in a sequential list, including things like checking out of hotels and returning rental cars by the designated time. A nice widget displays the next reservation. When I changed my plane flight to come home from Virginia early, it was very convenient to have in one listing all my reservations, their associated ID numbers, and the phone numbers of the provider so I didn't have to go digging through email or notes to know who to call and what reservation I had to cancel.
If you are a nostalgia buff, or just a big fan of an actor from the thirties or forties (Lucille Ball for me!), you may enjoy Old Time Radio. Lets you listen to entire episodes of old shows, and download them as MP3s for offline listening on airplanes and such.
For web browsing over Sprint's crummy 3G network, I find Opera Mini to be noticeably faster. It compresses the website you want to view before sending it to your phone, and seems to speed things up.
